MGASA-2023-0163 - Updated git packages fix security vulnerability

Publication date: 06 May 2023
URL: https://advisories.mageia.org/MGASA-2023-0163.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2023-25652,
     CVE-2023-25815,
     CVE-2023-29007

By feeding specially crafted input to 'git apply --reject', a path outside
the working tree can be overwritten with partially controlled contents
corresponding to the rejected hunk(s) from the given patch.
(CVE-2023-25652).

When Git is compiled with runtime prefix support and runs without
translated messages, it still used the gettext machinery to display
messages, which subsequently potentially looked for translated messages in
unexpected places. This allowed for malicious placement of crafted messages
(CVE-2023-25815).

When renaming or deleting a section from a configuration file, certain
malicious configuration values may be misinterpreted as the beginning of a
new configuration section, leading to arbitrary configuration injection
(CVE-2023-29007).
