SUSE Security Update: Security update for the Linux Kernel ______________________________________________________________________________ Announcement ID: SUSE-SU-2017:1628-1 Rating: critical References: #1018074 #1035920 #1039348 #1042921 #1043234 Cross-References: CVE-2017-1000364 Affected Products: SUSE Linux Enterprise Software Development Kit 11-SP4 SUSE Linux Enterprise Server 11-SP4 SUSE Linux Enterprise Server 11-EXTRA SUSE Linux Enterprise Debuginfo 11-SP4 ______________________________________________________________________________ An update that solves one vulnerability and has four fixes is now available. Description: The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-1000364: The default stack guard page was too small and could be "jumped over" by userland programs using more than one page of stack in functions and so lead to memory corruption. This update extends the stack guard page to 1 MB (for 4k pages) and 16 MB (for 64k pages) to reduce this attack vector. This is not a kernel bugfix, but a hardening measure against this kind of userland attack.(bsc#1039348) The following non-security bugs were fixed: - fnic now returns 'DID_IMM_RETRY' if rport is not ready (bsc#1035920). - fnic is now using rport->dd_data to check if rport is online instead of rport_lookup (bsc#1035920). - The rport check location in fnic_queuecommand_lck was corrected (bsc#1035920). - xfs: remove patches that caused regression (bsc#1043234). - mm: enlarge stack guard gap (bnc#1039348, CVE-2017-1000364, bnc#1042921). - PCI: Allow access to VPD attributes with size 0 (bsc#1018074).
