Affected Packages

Package Vulnerable Unaffected ----------------- ------------ ------------ app-admin/rsyslog < 8.2206.0 >= 8.2206.0

Impact

Modules for TCP syslog reception have a heap buffer overflow when octet- counted framing is used. The attacker can corrupt heap values, leading to data integrity issues and availability impact. Remote code execution is unlikely to happen but not impossible.

Workaround

There is no known workaround at this time.
