openSUSE-SU-2015:2289-1: moderate: Security update for openssl
openSUSE Security Update: Security update for openssl

Announcement ID: openSUSE-SU-2015:2289-1
Rating: moderate
References: #954256 #957812 #957813 #957815
Cross-References: CVE-2015-3194 CVE-2015-3195 CVE-2015-3196

Affected Products:
openSUSE Leap 42.1

An update that solves three vulnerabilities and has one
errata is now available.


This update for openssl fixes the following issues:

Security fixes:
- CVE-2015-3194: The signature verification routines will crash with a
NULL pointer dereference if presented with an ASN.1 signature using the
RSA PSS algorithm and absent mask generation function parameter. Since
these routines are used to verify certificate signature algorithms this
can be used to crash any certificate verification operation and
exploited in a DoS attack. Any application which performs certificate
verification is vulnerable including OpenSSL clients and servers which
enable client authentication. (bsc#957815)
- CVE-2015-3195: When presented with a malformed X509_ATTRIBUTE structure
OpenSSL would leak memory. This structure is used by the PKCS#7 and CMS
routines so any application which reads PKCS#7 or CMS data from
untrusted sources is affected. SSL/TLS is not affected. (bsc#957812)
- CVE-2015-3196: If PSK identity hints are received by a multi-threaded
client then the values were wrongly updated in the parent SSL_CTX
structure. This could result in a race condition potentially leading to
a double free of the identify hint data. (bsc#957813)

Non security bugs fixed:
- Improve S/390 performance on IBM z196 and z13 (bsc#954256)

This update was imported from the SUSE:SLE-12-SP1:Update update project.
