CWE-121  (opens in a new tab)

How to fix?

There is no fixed version for Centos:7 screen.

NVD Description

Note: Versions mentioned in the description apply only to the upstream screen package and not the screen package as distributed by Centos. See How to fix? for Centos:7 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.
