Two Debian 11 (Bullseye) LTS advisories have been issued to address security vulnerabilities. DLA-4079-2 fixes a regression in openvpn by allowing "\n" and "\r" characters in control channel messages and recommends upgrading to version 2.5.1-3+deb11u2. DLA-4286-1 addresses an uncontrolled recursion vulnerability (CVE-2025-48924) in the libcommons-lang3-java package by updating it to version 3.11-1+deb11u1. This vulnerability could lead to a StackOverflowError on very long inputs, and users are recommended to upgrade their packages. Additionally, an update for libcommons-lang-java has been released for both Debian 9 (Stretch) and 10 (Buster) ELTS.
