Mandriva Linux Security Advisory 2014-001

Posted Jan 13, 2014

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2014-001 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service via a VAPIC synchronization operation involving a page-end address. 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 via crafted modifications of the TMICT value. Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a XFS_IOC_ATTRLIST_BY_HANDLE or XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c. Various other issues have also been addressed.
