MGASA-2022-0457 - Updated emacs packages fix security vulnerability

Publication date: 13 Dec 2022
URL: https://advisories.mageia.org/MGASA-2022-0457.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-45939

GNU Emacs through 28.2 allows attackers to execute commands via shell
metacharacters in the name of a source-code file, because lib-src/etags.c
uses the system C library function in its implementation of the ctags
program. For example, a victim may use the "ctags *" command (suggested in
the ctags documentation) in a situation where the current working
directory has contents that depend on untrusted input. (CVE-2022-45939)
