Package : sudo
Version : 1.8.19p1-2.1+deb9u3
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 Debian 9 stretch, this problem has been fixed in version
1.8.19p1-2.1+deb9u3.

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
