Description

The following security issues have been fixed :

  • Specially crafted MIME headers could cause openssl's ans1 parser to dereference a NULL pointer leading to a Denial of Service (CVE-2006-7250) or fail verfication. (CVE-2012-1165)

  • The implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in OpenSSL was vulnerable to a Million Message Attack (MMA) adaptive chosen ciphertext attack. (CVE-2012-0884)

Additionally, the following issues have been fixed :

  • Free headers after use in error message. (bnc#749213)

  • Symmetric crypto errors in PKCS7_decrypt. (bnc#749210)

  • Memory leak when creating public keys. (bnc#749735)
