CVE-2020-9366

Name of the Vulnerable Software and Affected Versions GNU Screen versions prior to 4.8.0

Description A buffer overflow issue was discovered in the way GNU Screen handles the special escape OSC 49. This could be triggered by specially crafted output or a special program, potentially corrupting memory, crashing Screen, or having other unspecified impacts.

Recommendations For GNU Screen versions prior to 4.8.0, update to version 4.8.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the OSC 49 escape sequence until a patch is available.
