CVE-2022-48337: Debian Linux

Critical severity, CVSS 9.8. EPSS: 1.6% chance of exploitation in the next 30 days.

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 etags program. For example, a victim may use the "etags -u *" command (suggested in the etags documentation) in a situation where the current working directory has contents that depend on untrusted input.

Affected products

• Debian Debian Linux: version 11.0 only
• GNU Emacs: up to and including 28.2
