Synopsis:          Moderate: openssl security update
Advisory ID:       SLSA-2015:2617-1
Issue Date:        2015-12-14
CVE Numbers:       CVE-2015-3194
                   CVE-2015-3195
                   CVE-2015-3196
--

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)

For the update to take effect, all services linked to the OpenSSL library
must be restarted, or the system rebooted.
