Kuang-Che Wu

**Name of the Vulnerable Software and Affected Versions** GNU screen version 4.3.1 and earlier **Description** The issue is related to the MScrollV function in ansi.c, which does not properly limit recursion. This allows remote attackers to cause a denial of service, specifically stack consumption, via an escape sequence with a large repeat count value. **Recommendations** For GNU screen version 4.3.1 and earlier, consider updating to a newer version that addresses this issue. As a temporary workaround, restrict the use of the MScrollV function to minimize the risk of exploitation.
