| 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-2019-19126 | 3 Canonical, Fedoraproject, Gnu | 3 Ubuntu Linux, Fedora, Glibc | 2022-04-26 | 2.1 LOW | 3.3 LOW |
| On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program. | |||||

| 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. | |||||
| CVE-2020-12691 | 2 Canonical, Openstack | 2 Ubuntu Linux, Keystone | 2022-04-26 | 6.5 MEDIUM | 8.8 HIGH |
| An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to masquerade as another user. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges. | |||||
| CVE-2020-16166 | 7 Canonical, Debian, Fedoraproject and 4 more | 16 Ubuntu Linux, Debian Linux, Fedora and 13 more | 2022-04-26 | 4.3 MEDIUM | 3.7 LOW |

| CVE-2018-13405 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2022-02-25 | 4.6 MEDIUM | 7.8 HIGH |
| The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. | |||||
