Oracle Linux 5 / 6 : unbreakable enterprise kernel (ELSA-2013-2589)
medium Nessus Plugin ID 71515
Language:
Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-2589 advisory.- The do_tkill function in kernel/signal.c in the Linux kernel before 3.8.9 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted application that makes a (1) tkill or (2) tgkill system call. (CVE-2013-2141)
- The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c. (CVE-2013-4470)
- The apic_get_tmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via crafted modifications of the TMICT value. (CVE-2013-6367)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
