Description
Security update for the Linux Kernel The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. Following security bugs were fixed: - CVE-2015-7550: A local user could have triggered a race between read and revoke in keyctl (bnc#958951). - CVE-2015-8539: A negatively instantiated user key could have been used by a local user to leverage privileges (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: 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). - 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-2015-8569: 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-2015-8575: Validate socket address length in sco_sock_bind() to prevent information leak (bsc#959399).
