CentOS 8 : ctags (CESA-2023:2863)

high Nessus Plugin ID 175886

Language:

Synopsis

The remote CentOS host is missing a security update.

Description

The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2023:2863 advisory.

 - A flaw was found in Exuberant Ctags in the way it handles the -o option. This option specifies the tag filename. A crafted tag filename specified in the command line or in the configuration file results in arbitrary command execution because the externalSortTags() in sort.c calls the system(3) function in an unsafe way. (CVE-2022-4515)

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 ctags and / or ctags-etags packages.
