CVE-2011-3207: OpenSSL

Medium severity, CVSS 5.0. EPSS: 4.4% chance of exploitation in the next 30 days.

crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not initialize certain structure members, which makes it easier for remote attackers to bypass CRL validation by using a nextUpdate value corresponding to a time in the past.

Affected products
