openSUSE Security Update: Security update for the Linux Kernel ______________________________________________________________________________ Announcement ID: openSUSE-SU-2016:0280-1 Rating: important References: #865096 #865259 #913996 #950178 #950998 #952621 #954324 #954532 #954647 #955422 #956708 #957152 #957988 #957990 #958439 #958463 #958504 #958510 #958886 #958951 #959190 #959399 #960021 #960710 #961263 #961509 #962075 #962597 Cross-References: CVE-2015-7550 CVE-2015-8539 CVE-2015-8543 CVE-2015-8550 CVE-2015-8551 CVE-2015-8552 CVE-2015-8569 CVE-2015-8575 CVE-2015-8767 CVE-2016-0728 Affected Products: openSUSE Leap 42.1 ______________________________________________________________________________ An update that solves 10 vulnerabilities and has 18 fixes is now available. Description: The Linux kernel for openSUSE Leap 42.1 was updated to the 4.1.15 stable release, and also includes security and bugfixes. Following security bugs were fixed: - CVE-2016-0728: A reference leak in keyring handling with join_session_keyring() could lead to local attackers gain root privileges. (bsc#962075). - CVE-2015-7550: A local user could have triggered a race between read and revoke in keyctl (bnc#958951). - CVE-2015-8767: A case can occur when sctp_accept() is called by the user during a heartbeat timeout event after the 4-way handshake. Since sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the bh_sock_lock in sctp_generate_heartbeat_event() will be taken with the listening socket but released with the new association socket. The result is a deadlock on any future attempts to take the listening socket lock. (bsc#961509) - CVE-2015-8539: A negatively instantiated user key could have been used by a local user to leverage privileges (bnc#958463). - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel did not verify an address length, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application (bnc#959190). - CVE-2015-8543: The networking implementation in the Linux kernel did not validate protocol identifiers for certain protocol families, which allowed local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application (bnc#958886). - CVE-2015-8575: Validate socket address length in sco_sock_bind() to prevent information leak (bsc#959399). - CVE-2015-8551, CVE-2015-8552: xen/pciback: For XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled (bsc#957990). - CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers could have lead to double fetch vulnerabilities, causing denial of service or arbitrary code execution (depending on the configuration) (bsc#957988). The following non-security bugs were fixed: - ALSA: hda - Add a fixup for Thinkpad X1 Carbon 2nd (bsc#958439). - ALSA: hda - Apply click noise workaround for Thinkpads generically (bsc#958439). - ALSA: hda - Fix noise problems on Thinkpad T440s (boo#958504). - ALSA: hda - Flush the pending probe work at remove (boo#960710). - ALSA: hda - Set codec to D3 at reboot/shutdown on Thinkpads (bsc#958439). - Add Cavium Thunderx network enhancements - Add RHEL to kernel-obs-build - Backport amd xgbe fixes and features - Backport arm64 patches from SLE12-SP1-ARM. - Btrfs: fix the number of transaction units needed to remove a block group (bsc#950178). - Btrfs: use global reserve when deleting unused block group after ENOSPC (bsc#950178). - Documentation: nousb is a module parameter (bnc#954324). - Driver for IBM System i/p VNIC protocol. - Enable CONFIG_PINCTRL_CHERRYVIEW (boo#954532) Needed for recent tablets/laptops. CONFIG_PINCTRL_BAYTRAIL is still disabled as it can't be built as a module. - Fix PCI generic host controller - Fix kABI breakage for max_dev_sectors addition to queue_limits (boo#961263). - HID: multitouch: Fetch feature reports on demand for Win8 devices (boo#954532). - HID: multitouch: fix input mode switching on some Elan panels (boo#954532). - Implement enable/disable for Display C6 state (boo#960021). - Input: aiptek - fix crash on detecting device without endpoints (bnc#956708). - Linux 4.1.15 (boo#954647 bsc#955422). - Move kabi patch to patches.kabi directory - Obsolete compat-wireless, rts5229 and rts_pstor KMPs These are found in SLE11-SP3, now replaced with the upstream drivers. - PCI: generic: Pass starting bus number to pci_scan_root_bus(). - Revert "block: remove artifical max_hw_sectors cap" (boo#961263). - Set system time through RTC device - Update arm64 config files.
