Information from SSL-encrypted sessions via PKCS #1.

Heap-based buffer overflow in Netscape Network Security Services (NSS) library allows remote attackers to execute arbitrary code via a modified record length field in an SSLv2 client hello message.

A flaw was found in a way Red Hat Certificate System handled Extensions in the certificate signing requests (CSR). All requested Extensions were added to issued certificate despite constraints defined in Certificate Authority (CA) profile.

For example, CSR could contain Basic Constraints or Key Usage constraint that once copied to issued certificate would result in creation of subordinate CA certificate, even though CA configuration prohibits issuing of subordinate CA certificate, possibly leading to a bypass the intended security policy.

Affected versions: Red Hat Certificate System 7.1, 7.2, 7.3 Netscape Certificate Management System 6.x
