Amazon Linux 2 : (ALAS-2023-1928)

high Nessus Plugin ID 171048

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1928 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

pkg_manager = 'yum'Run ' update emacs' to update your system.
