CVE-2020-12768 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-04-27 2.1 LOW 5.5 MEDIUM
** DISPUTED ** An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will.
CVE-2020-15900 3 Artifex, Canonical, Opensuse 3 Ghostscript, Ubuntu Linux, Leap 2022-04-27 7.5 HIGH 9.8 CRITICAL
A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b.
CVE-2020-15780 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2022-04-27 7.2 HIGH 6.7 MEDIUM
An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30.
CVE-2020-8992 4 Canonical, Linux, Netapp and 1 more 11 Ubuntu Linux, Linux Kernel, Active Iq Unified Manager and 8 more 2022-04-27 4.9 MEDIUM 5.5 MEDIUM
ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.
CVE-2020-12692 2 Canonical, Openstack 2 Ubuntu Linux, Keystone 2022-04-27 5.5 MEDIUM 5.4 MEDIUM
An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times.
CVE-2020-3810 3 Canonical, Debian, Fedoraproject 4 Ubuntu Linux, Apt, Debian Linux and 1 more 2022-04-27 4.3 MEDIUM 5.5 MEDIUM
Missing input validation in the ar/tar implementations of APT before version 2.1.2 could result in denial of service when processing specially crafted deb files.
CVE-2020-13114 3 Canonical, Libexif Project, Opensuse 3 Ubuntu Linux, Libexif, Leap 2022-04-27 5.0 MEDIUM 7.5 HIGH
An issue was discovered in libexif before 0.6.22. An unrestricted size in handling Canon EXIF MakerNote data could lead to consumption of large amounts of compute time for decoding EXIF data.
CVE-2020-14093 4 Canonical, Debian, Mutt and 1 more 4 Ubuntu Linux, Debian Linux, Mutt and 1 more 2022-04-27 4.3 MEDIUM 5.9 MEDIUM
Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response.
CVE-2020-11736 3 Canonical, Debian, Gnome 3 Ubuntu Linux, Debian Linux, File-roller 2022-04-27 3.3 LOW 3.9 LOW
fr-archive-libarchive.c in GNOME file-roller through 3.36.1 allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink to a directory outside of the intended extraction location.
CVE-2020-13113 4 Canonical, Debian, Libexif Project and 1 more 4 Ubuntu Linux, Debian Linux, Libexif and 1 more 2022-04-26 6.4 MEDIUM 8.2 HIGH
An issue was discovered in libexif before 0.6.22. Use of uninitialized memory in EXIF Makernote handling could lead to crashes and potential use-after-free conditions.
CVE-2020-11526 4 Canonical, Debian, Freerdp and 1 more 4 Ubuntu Linux, Debian Linux, Freerdp and 1 more 2022-04-26 3.5 LOW 2.2 LOW
libfreerdp/core/update.c in FreeRDP versions > 1.1 through 2.0.0-rc4 has an Out-of-bounds Read.
CVE-2020-11521 4 Canonical, Debian, Freerdp and 1 more 4 Ubuntu Linux, Debian Linux, Freerdp and 1 more 2022-04-26 6.0 MEDIUM 6.6 MEDIUM
libfreerdp/codec/planar.c in FreeRDP version > 1.0 through 2.0.0-rc4 has an Out-of-bounds Write.
CVE-2020-6463 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2022-04-26 6.8 MEDIUM 8.8 HIGH
Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
CVE-2019-3813 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2022-04-26 5.4 MEDIUM 7.5 HIGH
Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers.
CVE-2019-12529 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-04-26 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages.
CVE-2019-12525 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-04-26 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1.
CVE-2019-12526 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-04-26 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap.
CVE-2019-12528 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-04-26 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes.
CVE-2020-12395 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2022-04-26 10.0 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR 68.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-12392 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2022-04-26 2.1 LOW 5.5 MEDIUM
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
