Debian Security Advisory DSA-4839-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
January 26, 2021 https://www.debian.org/security/faq

Package : sudo
CVE ID : CVE-2021-3156

The Qualys Research Labs discovered a heap-based buffer overflow
vulnerability in sudo, a program designed to provide limited super user
privileges to specific users. Any local user (sudoers and non-sudoers)
can exploit this flaw for root privilege escalation.

For the stable distribution (buster), this problem has been fixed in
version 1.8.27-1+deb10u3.

We recommend that you upgrade your sudo packages.

For the detailed security status of sudo please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/sudo

Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
found at: https://www.debian.org/security/
