Debian Security Advisory DSA-4861-1 security AT debian.org

Package : screen
CVE ID : CVE-2021-26937
Debian Bug : 982435
Felix Weinmann reported a flaw in the handling of combining characters
in screen, a terminal multiplexer with VT100/ANSI terminal emulation,
which can result in denial of service, or potentially the execution of
arbitrary code via a specially crafted UTF-8 character sequence.
For the stable distribution (buster), this problem has been fixed in
version 4.6.2-3+deb10u1.
We recommend that you upgrade your screen packages.
For the detailed security status of screen please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/screen
