CVE-2013-6367

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.

Severity: MEDIUM (5.7)Vector: AV:A/AC:M/Au:N/C:N/I:N/A:C

References:

The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address.

Severity: MEDIUM (6.2)Vector: AV:L/AC:H/Au:N/C:C/I:C/A:C

Package kernel-image-ovz-el updated to version 2.6.32-alt109 for branch sisyphus in task 111468.

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.

Severity: LOW (2.1)Vector: AV:L/AC:L/Au:N/C:P/I:N/A:N

References:

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.

Severity: MEDIUM (6.9)Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C

Stack-based buffer overflow in the bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont 1.1 through 1.4.6 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string in a character name in a BDF font file.
