CVE-2008-0062 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-02-09 9.3 HIGH 9.8 CRITICAL
KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.
CVE-2008-0063 7 Apple, Canonical, Debian and 4 more 11 Mac Os X, Mac Os X Server, Ubuntu Linux and 8 more 2024-02-09 4.3 MEDIUM 7.5 HIGH
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-2009-0949 5 Apple, Canonical, Debian and 2 more 7 Cups, Mac Os X, Mac Os X Server and 4 more 2024-02-09 5.0 MEDIUM 7.5 HIGH
The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags.
CVE-2009-2692 4 Debian, Linux, Redhat and 1 more 8 Debian Linux, Linux Kernel, Enterprise Linux Desktop and 5 more 2024-02-08 7.2 HIGH 7.8 HIGH
The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.
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-2022-27223 3 Debian, Linux, Netapp 17 Debian Linux, Linux Kernel, Active Iq Unified Manager and 14 more 2024-02-08 6.5 MEDIUM 8.8 HIGH
In drivers/usb/gadget/udc/udc-xilinx.c in the Linux kernel before 5.16.12, the endpoint index is not validated and might be manipulated by the host for out-of-array access.
CVE-2016-4029 2 Debian, Wordpress 2 Debian Linux, Wordpress 2024-02-08 5.0 MEDIUM 8.6 HIGH
WordPress before 4.5 does not consider octal and hexadecimal IP address formats when determining an intranet address, which allows remote attackers to bypass an intended SSRF protection mechanism via a crafted address.
CVE-2005-0102 2 Debian, Gnome 2 Debian Linux, Evolution 2024-02-08 7.2 HIGH 9.8 CRITICAL
Integer overflow in camel-lock-helper in Evolution 2.0.2 and earlier allows local users or remote malicious POP3 servers to execute arbitrary code via a length value of -1, which leads to a zero byte memory allocation and a buffer overflow.
CVE-2005-1513 3 Canonical, Debian, Qmail Project 3 Ubuntu Linux, Debian Linux, Qmail 2024-02-08 5.0 MEDIUM 9.8 CRITICAL
Integer overflow in the stralloc_readyplus function in qmail, when running on 64 bit platforms with a large amount of virtual memory, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large SMTP request.
CVE-2019-20916 4 Debian, Opensuse, Oracle and 1 more 5 Debian Linux, Leap, Communications Cloud Native Core Network Function Cloud Native Environment and 2 more 2024-02-08 5.0 MEDIUM 7.5 HIGH
The pip package before 19.2 for Python allows Directory Traversal when a URL is given in an install command, because a Content-Disposition header can have ../ in a filename, as demonstrated by overwriting the /root/.ssh/authorized_keys file. This occurs in _download_http_url in _internal/download.py.
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.
