Mandriva Linux Security Advisory : kernel (MDVSA-2014:001)

High Nessus Plugin ID 71936

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

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 (system crash) via a VAPIC synchronization operation involving a page-end address (CVE-2013-6368).

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).

Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) 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 (CVE-2013-6382).

Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value (CVE-2013-4587).

The mISDN_sock_recvmsg function in drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does not ensure that a certain length value is consistent with the size of an associated data structure, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7266).

The atalk_recvmsg function in net/appletalk/ddp.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7267).

The ipx_recvmsg function in net/ipx/af_ipx.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7268).

The nr_recvmsg function in net/netrom/af_netrom.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7269).

The packet_recvmsg function in net/packet/af_packet.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 memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7270).

The x25_recvmsg function in net/x25/af_x25.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7271).

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 l2tp_ip_recvmsg function in net/l2tp/l2tp_ip.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-2013-7264).

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).

The dgram_recvmsg function in net/ieee802154/dgram.c in the Linux kernel before 3.12.4 updates a certain length value without 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-2013-7281).

The updated packages provides a solution for these security issues.
