 ------------------------------------------------------------------------- Debian LTS Advisory DLA-4079-2 [email protected] https://www.debian.org/lts/security/ Carlos Henrique Lima Melara August 31, 2025 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : openvpn Version : 2.5.1-3+deb11u2 CVE ID :
 Debian Bug : 1112516

 The upstream fix for CVE-2024-5594 released in DLA-4079-1 restricted characters in control channel messages including \n and \r, but many scripts add them.
 This regression fix basically allows \n and \r in the control channel messages.

 For Debian 11 bullseye, this problem has been fixed in version 2.5.1-3+deb11u2.

 We recommend that you upgrade your openvpn packages.
