CVE-2015-6806  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade Debian:12 screen to version 4.3.1-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream screen package and not the screen package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

The MScrollV function in ansi.c in GNU screen 4.3.1 and earlier does not properly limit recursion, which allows remote attackers to cause a denial of service (stack consumption) via an escape sequence with a large repeat count value.
