CVE-2019-17451 3 Canonical, Gnu, Opensuse 3 Ubuntu Linux, Binutils, Leap 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an integer overflow leading to a SEGV in _bfd_dwarf2_find_nearest_line in dwarf2.c, as demonstrated by nm.
CVE-2019-18218 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).
CVE-2019-17055 6 Canonical, Debian, Fedoraproject and 3 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2023-11-07 2.1 LOW 3.3 LOW
base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21.
CVE-2019-18425 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 9.3 HIGH 9.8 CRITICAL
An issue was discovered in Xen through 4.12.x allowing 32-bit PV guest OS users to gain guest OS privileges by installing and using descriptors. There is missing descriptor table limit checking in x86 PV emulation. When emulating certain PV guest operations, descriptor table accesses are performed by the emulating code. Such accesses should respect the guest specified limits, unless otherwise guaranteed to fail in such a case. Without this, emulation of 32-bit guest user mode calls through call gates would allow guest user mode to install and then use descriptors of their choice, as long as the guest kernel did not itself install an LDT. (Most OSes don't install any LDT by default). 32-bit PV guest user mode can elevate its privileges to that of the guest kernel. Xen versions from at least 3.2 onwards are affected. Only 32-bit PV guest user mode can leverage this vulnerability. HVM, PVH, as well as 64-bit PV guests cannot leverage this vulnerability. Arm systems are unaffected.
CVE-2019-17569 5 Apache, Debian, Netapp and 2 more 16 Tomcat, Tomee, Debian Linux and 13 more 2023-11-07 5.8 MEDIUM 4.8 MEDIUM
The refactoring present in Apache Tomcat 9.0.28 to 9.0.30, 8.5.48 to 8.5.50 and 7.0.98 to 7.0.99 introduced a regression. The result of the regression was that invalid Transfer-Encoding headers were incorrectly processed leading to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
CVE-2019-17563 5 Apache, Canonical, Debian and 2 more 11 Tomcat, Ubuntu Linux, Debian Linux and 8 more 2023-11-07 5.1 MEDIUM 7.5 HIGH
When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability.
CVE-2019-18421 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 7.1 HIGH 7.5 HIGH
An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen exposes the actual hardware pagetables to the guest. In order to prevent the guest from modifying these page tables directly, Xen keeps track of how pages are used using a type system; pages must be "promoted" before being used as a pagetable, and "demoted" before being used for any other type. Xen also allows for "recursive" promotions: i.e., an operating system promoting a page to an L4 pagetable may end up causing pages to be promoted to L3s, which may in turn cause pages to be promoted to L2s, and so on. These operations may take an arbitrarily large amount of time, and so must be re-startable. Unfortunately, making recursive pagetable promotion and demotion operations restartable is incredibly complicated, and the code contains several races which, if triggered, can cause Xen to drop or retain extra type counts, potentially allowing guests to get write access to in-use pagetables. A malicious PV guest administrator may be able to escalate their privilege to that of the host. All x86 systems with untrusted PV guests are vulnerable. HVM and PVH guests cannot exercise this vulnerability.
CVE-2019-17041 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap overflow in the parser for AIX log messages. The parser tries to locate a log message delimiter (in this case, a space or a colon) but fails to account for strings that do not satisfy this constraint. If the string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check that detects invalid log messages. The message will then be considered valid, and the parser will eat up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. The following step in the parser is to shift left the contents of the message. To do this, it will call memmove with the right pointers to the target and destination strings, but the lenMsg will now be interpreted as a huge value, causing a heap overflow.
CVE-2019-18424 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 6.9 MEDIUM 6.8 MEDIUM
An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device. This occurs because passed through PCI devices may corrupt host memory after deassignment. When a PCI device is assigned to an untrusted domain, it is possible for that domain to program the device to DMA to an arbitrary address. The IOMMU is used to protect the host from malicious DMA by making sure that the device addresses can only target memory assigned to the guest. However, when the guest domain is torn down, or the device is deassigned, the device is assigned back to dom0, thus allowing any in-flight DMA to potentially target critical host data. An untrusted domain with access to a physical device can DMA into host memory, leading to privilege escalation. Only systems where guests are given direct access to physical devices capable of DMA (PCI pass-through) are vulnerable. Systems which do not use PCI pass-through are not vulnerable.

CVE-2019-18660 5 Canonical, Fedoraproject, Linux and 2 more 5 Ubuntu Linux, Fedora, Linux Kernel and 2 more 2023-11-07 1.9 LOW 4.7 MEDIUM
The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c.
CVE-2019-15143 5 Canonical, Debian, Djvulibre Project and 2 more 5 Ubuntu Linux, Debian Linux, Djvulibre and 2 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
In DjVuLibre 3.5.27, the bitmap reader component allows attackers to cause a denial-of-service error (resource exhaustion caused by a GBitmap::read_rle_raw infinite loop) by crafting a corrupted image file, related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp.
CVE-2019-14889 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 9.3 HIGH 8.8 HIGH
A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.
CVE-2019-15666 3 Debian, Linux, Opensuse 3 Debian Linux, Linux Kernel, Leap 2023-11-07 4.9 MEDIUM 4.4 MEDIUM
An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation.
CVE-2019-16776 5 Fedoraproject, Npmjs, Opensuse and 2 more 6 Fedora, Npm, Leap and 3 more 2023-11-07 5.5 MEDIUM 8.1 HIGH
Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It fails to prevent access to folders outside of the intended node_modules folder through the bin field. A properly constructed entry in the package.json bin field would allow a package publisher to modify and/or gain access to arbitrary files on a user's system when the package is installed. This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
CVE-2019-14811 5 Artifex, Debian, Fedoraproject and 2 more 5 Ghostscript, Debian Linux, Fedora and 2 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
A flaw was found in, ghostscript versions prior to 9.50, in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.
CVE-2019-16777 5 Fedoraproject, Npmjs, Opensuse and 2 more 6 Fedora, Npm, Leap and 3 more 2023-11-07 5.5 MEDIUM 6.5 MEDIUM
Versions of the npm CLI prior to 6.13.4 are vulnerable to an Arbitrary File Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the previous serve binary. This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
CVE-2019-15145 5 Canonical, Debian, Djvulibre Project and 2 more 5 Ubuntu Linux, Debian Linux, Djvulibre and 2 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-bounds read) by crafting a corrupted JB2 image file that is mishandled in JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h because of a missing zero-bytes check in libdjvu/GBitmap.h.
CVE-2019-16276 6 Debian, Fedoraproject, Golang and 3 more 9 Debian Linux, Fedora, Go and 6 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling.
CVE-2019-14833 3 Fedoraproject, Opensuse, Samba 3 Fedora, Leap, Samba 2023-11-07 4.9 MEDIUM 5.4 MEDIUM
A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks.
