Description

The remote host is affected by the vulnerability described in GLSA-202208-22 (xterm: Multiple Vulnerabilities)

- xterm before Patch #366 allows remote attackers to execute arbitrary code or cause a denial of service (segmentation fault) via a crafted UTF-8 combining character sequence. (CVE-2021-27135)

- xterm through Patch 370, when Sixel support is enabled, allows attackers to trigger a buffer overflow in set_sixel in graphics_sixel.c via crafted text. (CVE-2022-24130)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

All xterm users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=x11-terms/xterm-371
