 Mandriva Linux Security Advisory                         MDVSA-2013:291
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : kernel
 Date    : December 17, 2013
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in the Linux
 kernel:
 
 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 perf_trace_event_perm function in kernel/trace/trace_event_perf.c
 in the Linux kernel before 3.12.2 does not properly restrict access
 to the perf subsystem, which allows local users to enable function
 tracing via a crafted application (CVE-2013-2930).
 
 Multiple integer overflows in Alchemy LCD frame-buffer drivers in the
 Linux kernel before 3.12 allow local users to create a read-write
 memory mapping for the entirety of kernel memory, and consequently
 gain privileges, via crafted mmap operations, related to the (1)
 au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2)
 au1200fb_fb_mmap function in drivers/video/au1200fb.c (CVE-2013-4511).
 
 Buffer overflow in the exitcode_proc_write function in
 arch/um/kernel/exitcode.c in the Linux kernel before 3.12 allows
 local users to cause a denial of service or possibly have unspecified
 other impact by leveraging root privileges for a write operation
 (CVE-2013-4512).
 
 Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c
 in the Linux kernel before 3.12 allow local users to cause a
 denial of service or possibly have unspecified other impact
 by leveraging the CAP_NET_ADMIN capability and providing a long
 station-name string, related to the (1) wvlan_uil_put_info and (2)
 wvlan_set_station_nickname functions (CVE-2013-4514).
 
 The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in
 the Linux kernel before 3.12 does not initialize a certain data
 structure, which allows local users to obtain sensitive information
 from kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call
 (CVE-2013-4515).
 
 Memory leak in the __kvm_set_memory_region function in
 virt/kvm/kvm_main.c in the Linux kernel before 3.9 allows local users
 to cause a denial of service (memory consumption) by leveraging certain
 device access to trigger movement of memory slots (CVE-2013-4592).
 
 The lbs_debugfs_write function in
 drivers/net/wireless/libertas/debugfs.c in the Linux kernel through
 3.12.1 allows local users to cause a denial of service (OOPS)
 by leveraging root privileges for a zero-length write operation
 (CVE-2013-6378).
 
 The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in
 the Linux kernel through 3.12.1 does not properly validate a certain
 size value, which allows local users to cause a denial of service
 (invalid pointer dereference) or possibly have unspecified other
 impact via an FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted
 SRB command (CVE-2013-6380).
 
 Buffer overflow in the qeth_snmp_command function in
 drivers/s390/net/qeth_core_main.c in the Linux kernel through 3.12.1
 allows local users to cause a denial of service or possibly have
 unspecified other impact via an SNMP ioctl call with a length value
 that is incompatible with the command-buffer size (CVE-2013-6381).
 
 The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in
 the Linux kernel before 3.11.8 does not require the CAP_SYS_RAWIO
 capability, which allows local users to bypass intended access
 restrictions via a crafted ioctl call (CVE-2013-6383).
 
 The uio_mmap_physical function in drivers/uio/uio.c in the Linux
 kernel before 3.12 does not validate the size of a memory block, which
 allows local users to cause a denial of service (memory corruption)
 or possibly gain privileges via crafted mmap operations, a different
 vulnerability than CVE-2013-4511 (CVE-2013-6763).
 
 The updated packages provides a solution for these security issues.
