Package : librelp
CVE ID : CVE-2018-1000140
Bas van Schaik and Kevin Backhouse discovered a stack-based buffer
overflow vulnerability in librelp, a library providing reliable event
logging over the network, triggered while checking x509 certificates
from a peer. A remote attacker able to connect to rsyslog can take
advantage of this flaw for remote code execution by sending a specially
crafted x509 certificate.
Details can be found in the upstream advisory:
http://www.rsyslog.com/cve-2018-1000140/
For the oldstable distribution (jessie), this problem has been fixed
in version 1.2.7-2+deb8u1.
