Debian DLA-3254-1 : exuberant-ctags - LTS security update

high Nessus Plugin ID 169439

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3254 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

Upgrade the exuberant-ctags packages.

For Debian 10 Buster, this problem has been fixed in version 1
