28 March 2018

  • librelp - Reliable Event Logging Protocol (RELP) library


Bas van Schaik and Kevin Backhouse discovered that librelp incorrectly
handled checking certain x509 certificates. A remote attacker able to
connect to rsyslog could possibly use this issue to execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04

After a standard system update you need to restart rsyslog to make all the
necessary changes.
