 Mandriva Linux Security Advisory                         MDVSA-2014:155
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : kernel
 Date    : August 7, 2014
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in the Linux
 kernel:
 
 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).
 
 Use-after-free vulnerability in the skb_segment function in
 net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers
 to obtain sensitive information from kernel memory by leveraging the
 absence of a certain orphaning operation (CVE-2014-0131).
 
 The rd_build_device_space function in drivers/target/target_core_rd.c
 in the Linux kernel before 3.14 does not properly initialize a
 certain data structure, which allows local users to obtain sensitive
 information from ramdisk_mcp memory by leveraging access to a SCSI
 initiator (CVE-2014-4027).
 
 Multiple integer overflows in the lzo1x_decompress_safe function in
 lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux
 kernel before 3.15.2 allow context-dependent attackers to cause
 a denial of service (memory corruption) via a crafted Literal Run
 (CVE-2014-4608).
 
 Race condition in the tlv handler functionality in the
 snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA
 control implementation in the Linux kernel before 3.15.2 allows local
 users to obtain sensitive information from kernel memory by leveraging
 /dev/snd/controlCX access (CVE-2014-4652).
 
 sound/core/control.c in the ALSA control implementation in the Linux
 kernel before 3.15.2 does not ensure possession of a read/write lock,
 which allows local users to cause a denial of service (use-after-free)
 and obtain sensitive information from kernel memory by leveraging
 /dev/snd/controlCX access (CVE-2014-4653).
 
 The snd_ctl_elem_add function in sound/core/control.c in the ALSA
 control implementation in the Linux kernel before 3.15.2 does not check
 authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows
 local users to remove kernel controls and cause a denial of service
 (use-after-free and system crash) by leveraging /dev/snd/controlCX
 access for an ioctl call (CVE-2014-4654).
 
 The snd_ctl_elem_add function in sound/core/control.c in the ALSA
 control implementation in the Linux kernel before 3.15.2 does not
 properly maintain the user_ctl_count value, which allows local users
 to cause a denial of service (integer overflow and limit bypass)
 by leveraging /dev/snd/controlCX access for a large number of
 SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls (CVE-2014-4655).
 
 Multiple integer overflows in sound/core/control.c in the ALSA control
 implementation in the Linux kernel before 3.15.2 allow local users
 to cause a denial of service by leveraging /dev/snd/controlCX access,
 related to (1) index values in the snd_ctl_add function and (2) numid
 values in the snd_ctl_remove_numid_conflict function (CVE-2014-4656).
 
 The sctp_association_free function in net/sctp/associola.c in the
 Linux kernel before 3.15.2 does not properly manage a certain backlog
 value, which allows remote attackers to cause a denial of service
 (socket outage) via a crafted SCTP packet (CVE-2014-4667).
 
 The Linux kernel before 3.15.4 on Intel processors does not properly
 restrict use of a non-canonical value for the saved RIP address in
 the case of a system call that does not use IRET, which allows local
 users to leverage a race condition and gain privileges, or cause
 a denial of service (double fault), via a crafted application that
 makes ptrace and fork system calls (CVE-2014-4699).
 
 The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel
 through 3.15.6 allows local users to gain privileges by leveraging
 data-structure differences between an l2tp socket and an inet socket
 (CVE-2014-4943).
 
 The updated packages provides a solution for these security issues.
