Summary
Martin Thomson discovered that nss, the Mozilla Network Security Service library, is prone to a use-after-free vulnerability in the TLS 1.2 implementation when handshake hashes are generated. A remote attacker can take advantage of this flaw to cause an application using the nss library to crash, resulting in a denial of service, or potentially to execute arbitrary code.
