  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.53 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the
 Linux kernel allowed local users to bypass intended AF_UNIX socket
 permissions or cause a denial of service (panic) via crafted epoll_ctl
 calls (bnc#955654).
- CVE-2015-5707: Integer overflow in the sg_start_req function in
 drivers/scsi/sg.c in the Linux kernel allowed local users to cause a
 denial of service or possibly have unspecified other impact via a large
 iov_count value in a write request (bnc#940338).
- CVE-2015-7550: The keyctl_read_key function in security/keys/keyctl.c in
 the Linux kernel did not properly use a semaphore, which allowed local
 users to cause a denial of service (NULL pointer dereference and system
 crash) or possibly have unspecified other impact via a crafted
 application that leverages a race condition between keyctl_revoke and
 keyctl_read calls (bnc#958951).
- CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the
 Linux kernel did not ensure that certain slot numbers are valid, which
 allowed local users to cause a denial of service (NULL pointer
 dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call
 (bnc#949936).
- CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel
 did not validate attempted changes to the MTU value, which allowed
 context-dependent attackers to cause a denial of service (packet loss)
 via a value that was (1) smaller than the minimum compliant value or (2)
 larger than the MTU of an interface, as demonstrated by a Router
 Advertisement (RA) message that is not validated by a daemon, a
 different vulnerability than CVE-2015-0272 (bnc#955354).
- CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local
 users to gain privileges or cause a denial of service (BUG) via crafted
 keyctl commands that negatively instantiate a key, related to
 security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and
 security/keys/user_defined.c (bnc#958463).
- 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-2015-8550: Optimizations introduced by the compiler could have lead
 to double fetch vulnerabilities, potentially possibly leading to
 arbitrary code execution in backend (bsc#957988).
- CVE-2015-8551: Xen PCI backend driver did not perform proper sanity
 checks on the device's state, allowing for DoS (bsc#957990).
- CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in
 drivers/net/ppp/pptp.c in the Linux ... [Please see the references for more information on the vulnerabilities]");
