Ubuntu 16.04 ESM : Emacs vulnerability (USN-5781-1)

high Nessus Plugin ID 168744

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5781-1 advisory.

 - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
