Description Vincent Danen 2012-01-04 22:35:03 UTC

Double-free in Policy Checks (CVE-2011-4109)
============================================

If X509_V_FLAG_POLICY_CHECK is set in OpenSSL 0.9.8, then a policy
check failure can lead to a double-free. The bug does not occur 
unless this flag is set. Users of OpenSSL 1.0.0 are not affected.

This flaw was discovered by Ben Laurie and a fix provided by Emilia
Kasper <ekasper> of Google.

Affected users should upgrade to OpenSSL 0.9.8s.

The affected functions are not present in openssl 0.9.7a either, so Red Hat Enterprise Linux 4 is not affected by this flaw either.
