Amazon Linux 2 Security Advisory: ALAS-2023-1928
Advisory Release Date: 2023-01-30 16:03 Pacific
Advisory Updated Date: 2023-02-04 18:28 Pacific
Severity:
Important
Issue Overview:
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)
Affected Packages:
emacs
Note:
