ALAS-2015-614


Amazon Linux AMI Security Advisory: ALAS-2015-614
Advisory Release Date: 2015-12-13 14:15 Pacific
Severity: Medium

Issue Overview:

A NULL pointer derefernce flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacked could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication. (CVE-2015-3194 )

A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. (CVE-2015-3195 )

A race condition flaw, leading to a double free, was found in the way OpenSSL handled pre-shared key (PSK) identify hints. A remote attacker could use this flaw to crash a multi-threaded SSL/TLS client using OpenSSL. (CVE-2015-3196 )
