  • A buffer overflow flaw was found in the way the qeth_snmp_command() function in the Linux kernel’s QETH network device driver implementation handled SNMP IOCTL requests with an out-of-bounds length. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
    (CVE-2013-6381, Important)

  • A flaw was found in the way the get_dumpable() function return value was interpreted in the ptrace subsystem of the Linux kernel. When ‘fs.suid_dumpable’ was set to 2, a local, unprivileged local user could use this flaw to bypass intended ptrace restrictions and obtain potentially sensitive information. (CVE-2013-2929, Low)

  • It was found that certain protocol handlers in the Linux kernel’s networking implementation could set the addr_len value without initializing the associated data structure. A local, unprivileged user could use this flaw to leak kernel stack memory to user space using the recvmsg, recvfrom, and recvmmsg system calls (CVE-2013-7263, CVE-2013-7265, Low).

The system must be rebooted for this update to take effect.
