| The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values." | |||||
| CVE-2009-3620 | 6 Canonical, Fedoraproject, Linux and 3 more | 8 Ubuntu Linux, Fedora, Linux Kernel and 5 more | 2024-02-09 | 4.9 MEDIUM | 7.8 HIGH |
| The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. | |||||
| CVE-2020-20739 | 3 Debian, Fedoraproject, Libvips | 3 Debian Linux, Fedora, Libvips | 2024-02-08 | 5.0 MEDIUM | 5.3 MEDIUM |
| im_vips2dz in /libvips/libvips/deprecated/im_vips2dz.c in libvips before 8.8.2 has an uninitialized variable which may cause the leakage of remote server path or stack address. | |||||
| CVE-2010-1637 | 4 Apple, Fedoraproject, Redhat and 1 more | 7 Mac Os X, Mac Os X Server, Fedora and 4 more | 2024-02-08 | 4.0 MEDIUM | 6.5 MEDIUM |
| The Mail Fetch plugin in SquirrelMail 1.4.20 and earlier allows remote authenticated users to bypass firewall restrictions and use SquirrelMail as a proxy to scan internal networks via a modified POP3 port number. | |||||
| CVE-2017-15129 | 4 Canonical, Fedoraproject, Linux and 1 more | 20 Ubuntu Linux, Fedora, Linux Kernel and 17 more | 2024-02-08 | 4.9 MEDIUM | 4.7 MEDIUM |
| A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely. | |||||
| CVE-2022-21668 | 2 Fedoraproject, Pypa | 2 Fedora, Pipenv | 2024-02-07 | 9.3 HIGH | 8.6 HIGH |
| pipenv is a Python development workflow tool. Starting with version 2018.10.9 and prior to version 2022.1.8, a flaw in pipenv's parsing of requirements files allows an attacker to insert a specially crafted string inside a comment anywhere within a requirements.txt file, which will cause victims who use pipenv to install the requirements file to download dependencies from a package index server controlled by the attacker. By embedding malicious code in packages served from their malicious index server, the attacker can trigger arbitrary remote code execution (RCE) on the victims' systems. If an attacker is able to hide a malicious `--index-url` option in a requirements file that a victim installs with pipenv, the attacker can embed arbitrary malicious code in packages served from their malicious index server that will be executed on the victim's host during installation (remote code execution/RCE). When pip installs from a source distribution, any code in the setup.py is executed by the install process. This issue is patched in version 2022.1.8. The GitHub Security Advisory contains more information about this vulnerability. | |||||
| CVE-2023-6238 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-02-07 | N/A | 6.7 MEDIUM |
| A buffer overflow vulnerability was found in the NVM Express (NVMe) driver in the Linux kernel. Only privileged user could specify a small meta buffer and let the device perform larger Direct Memory Access (DMA) into the same buffer, overwriting unrelated kernel memory, causing random kernel crashes and memory corruption. | |||||
| CVE-2022-26496 | 3 Debian, Fedoraproject, Network Block Device Project | 3 Debian Linux, Fedora, Network Block Device | 2024-02-04 | 7.5 HIGH | 9.8 CRITICAL |
| In nbd-server in nbd before 3.24, there is a stack-based buffer overflow. An attacker can cause a buffer overflow in the parsing of the name field by sending a crafted NBD_OPT_INFO or NBD_OPT_GO message with an large value as the length of the name. | |||||
| CVE-2022-26495 | 3 Debian, Fedoraproject, Network Block Device Project | 3 Debian Linux, Fedora, Network Block Device | 2024-02-04 | 7.5 HIGH | 9.8 CRITICAL |
| In nbd-server in nbd before 3.24, there is an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name, resulting in a write to a dangling pointer. This issue exists for the NBD_OPT_INFO, NBD_OPT_GO, and NBD_OPT_EXPORT_NAME messages. | |||||
| CVE-2021-28704 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | 6.9 MEDIUM | 8.8 HIGH |
| PoD operations on misaligned GFNs T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). The implementation of some of these hypercalls for PoD does not enforce the base page frame number to be suitably aligned for the specified order, yet some code involved in PoD handling actually makes such an assumption. These operations are XENMEM_decrease_reservation (CVE-2021-28704) and XENMEM_populate_physmap (CVE-2021-28707), the latter usable only by domains controlling the guest, i.e. a de-privileged qemu or a stub domain. (Patch 1, combining the fix to both these two issues.) In addition handling of XENMEM_decrease_reservation can also trigger a host crash when the specified page order is neither 4k nor 2M nor 1G (CVE-2021-28708, patch 2). | |||||
| CVE-2021-28705 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | 6.9 MEDIUM | 7.8 HIGH |
| issues with partially successful P2M updates on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). In some cases the hypervisor carries out the requests by splitting them into smaller chunks. Error handling in certain PoD cases has been insufficient in that in particular partial success of some operations was not properly accounted for. There are two code paths affected - page removal (CVE-2021-28705) and insertion of new pages (CVE-2021-28709). (We provide one patch which combines the fix to both issues.) | |||||
| CVE-2021-28706 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | 7.8 HIGH | 8.6 HIGH |
| guests may exceed their designated memory limit When a guest is permitted to have close to 16TiB of memory, it may be able to issue hypercalls to increase its memory allocation beyond the administrator established limit. This is a result of a calculation done with 32-bit precision, which may overflow. It would then only be the overflowed (and hence small) number which gets compared against the established upper bound. | |||||
| CVE-2022-42325 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | N/A | 5.5 MEDIUM |
| Xenstore: Guests can create arbitrary number of nodes via transactions T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] In case a node has been created in a transaction and it is later deleted in the same transaction, the transaction will be terminated with an error. As this error is encountered only when handling the deleted node at transaction finalization, the transaction will have been performed partially and without updating the accounting information. This will enable a malicious guest to create arbitrary number of nodes. | |||||
| CVE-2022-42333 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | N/A | 8.6 HIGH |
| x86/HVM pinned cache attributes mis-handling T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] To allow cachability control for HVM guests with passed through devices, an interface exists to explicitly override defaults which would otherwise be put in place. While not exposed to the affected guests themselves, the interface specifically exists for domains controlling such guests. This interface may therefore be used by not fully privileged entities, e.g. qemu running deprivileged in Dom0 or qemu running in a so called stub-domain. With this exposure it is an issue that - the number of the such controlled regions was unbounded (CVE-2022-42333), - installation and removal of such regions was not properly serialized (CVE-2022-42334). | |||||
| CVE-2022-42323 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | N/A | 5.5 MEDIUM |
| Xenstore: Cooperating guests can create arbitrary numbers of nodes T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Since the fix of XSA-322 any Xenstore node owned by a removed domain will be modified to be owned by Dom0. This will allow two malicious guests working together to create an arbitrary number of Xenstore nodes. This is possible by domain A letting domain B write into domain A's local Xenstore tree. Domain B can then create many nodes and reboot. The nodes created by domain B will now be owned by Dom0. By repeating this process over and over again an arbitrary number of nodes can be created, as Dom0's number of nodes isn't limited by Xenstore quota. | |||||
| CVE-2022-42324 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | N/A | 5.5 MEDIUM |
| Oxenstored 32->31 bit integer truncation issues Integers in Ocaml are 63 or 31 bits of signed precision. The Ocaml Xenbus library takes a C uint32_t out of the ring and casts it directly to an Ocaml integer. In 64-bit Ocaml builds this is fine, but in 32-bit builds, it truncates off the most significant bit, and then creates unsigned/signed confusion in the remainder. This in turn can feed a negative value into logic not expecting a negative value, resulting in unexpected exceptions being thrown. The unexpected exception is not handled suitably, creating a busy-loop trying (and failing) to take the bad packet out of the xenstore ring. | |||||
| CVE-2022-42320 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | N/A | 7.0 HIGH |
| Xenstore: Guests can get access to Xenstore nodes of deleted domains Access rights of Xenstore nodes are per domid. When a domain is gone, there might be Xenstore nodes left with access rights containing the domid of the removed domain. This is normally no problem, as those access right entries will be corrected when such a node is written later. There is a small time window when a new domain is created, where the access rights of a past domain with the same domid as the new one will be regarded to be still valid, leading to the new domain being able to get access to a node which was meant to be accessible by the removed domain. For this to happen another domain needs to write the node before the newly created domain is being introduced to Xenstore by dom0. | |||||
| CVE-2022-42319 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-02-04 | N/A | 6.5 MEDIUM |
| Xenstore: Guests can cause Xenstore to not free temporary memory When working on a request of a guest, xenstored might need to allocate quite large amounts of memory temporarily. This memory is freed only after the request has been finished completely. A request is regarded to be finished only after the guest has read the response message of the request from the ring page. Thus a guest not reading the response can cause xenstored to not free the temporary memory. This can result in memory shortages causing Denial of Service (DoS) of xenstored. | |||||
