Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2023:0225-1 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 package.
