Description Huzaifa S. Sidhpurwala 2017-06-01 08:55:57 UTC
Several memory leak flaws were found in Exim. A local attacker who has access to run the exim binary could use this flaw to escalate his privilege to root.

Comment 7 Huzaifa S. Sidhpurwala 2017-06-21 08:24:12 UTC

Exim itself is not vulnerable to privilege escalation, but this particular flaw in exim can be used by the stackguard vulnerability (https://access.redhat.com/security/vulnerabilities/stackguard) to achieve privilege escalation.
