"The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in
the ELSA-2014-3010 advisory.

  - The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users
    to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a
    crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h. (CVE-2013-2929)

  - The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data
    structures have been initialized, which allows local users to obtain sensitive information from kernel
    stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call, related to net/ipv4/ping.c,
    net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c. (CVE-2013-7263)

  - The pn_recvmsg function in net/phonet/datagram.c in the Linux kernel before 3.12.4 updates a certain
    length value before ensuring that an associated data structure has been initialized, which allows local
    users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3)
    recvmsg system call. (CVE-2013-7265)
