Description

This update for openssl fixes the following issues contained in the OpenSSL Security Advisory [26 Jan 2017] (bsc#1021641) Security issues fixed :

  • CVE-2016-7055: The x86_64 optimized montgomery multiplication may produce incorrect results (bsc#1009528)

  • CVE-2017-3731: Truncated packet could crash via OOB read (bsc#1022085)

  • CVE-2017-3732: BN_mod_exp may produce incorrect results on x86_64 (bsc#1022086)

  • Degrade the 3DES cipher to MEDIUM in SSLv2 (bsc#1001912) Non-security issues fixed :

  • fix crash in openssl speed (bsc#1000677)

  • fix X509_CERT_FILE path (bsc#1022271)

  • AES XTS key parts must not be identical in FIPS mode (bsc#1019637)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
