Description

A vulnerability was found in the OCSP search functionality in stunnel that could allow a remote attacker to use a revoked certificate that would be successfully authenticated by stunnel (CVE-2008-2420). This flaw only concerns users who have enabled OCSP validation in stunnel.

The updated packages have been patched to correct this issue.
