Debian DLA-2558-2 : xterm regression update

critical Nessus Plugin ID 146521

Language:

Synopsis

The remote Debian host is missing a security update.

Description

DLA 2558-2 backported a part of the upstream patch which fails to deal with the realloc failures in Debian stretch. This update reverts that part of the patch since it's not really needed and just focuses on fixing CVE-2021-27135.

For Debian 9 stretch, this problem has been fixed in version 327-2+deb9u2.

We recommend that you upgrade your xterm packages.

For the detailed security status of xterm please refer to its security tracker page at: https://security-tracker.debian.org/tracker/xterm

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected xterm package.
