CVE-2011-1477: Multiple array index errors in sound/oss/opl3.c in the Linux kernel allowed local users to cause a denial of service (heap memory corruption) or possibly gain privileges by leveraging write access to /dev/sequencer (bnc#681999).

CVE-2011-1163: The osf_partition function in fs/partitions/osf.c in the Linux kernel did not properly handle an invalid number of partitions, which might allow local users to obtain potentially sensitive information from kernel heap memory via vectors related to partition-table parsing (bnc#679812).

CVE-2011-1090: The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel stored NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allowed local users to cause a denial of service (panic) via a crafted attempt to set an ACL (bnc#677286).

CVE-2014-9584: The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel did not validate a length value in the Extensions Reference (ER) System Use Field, which allowed local users to obtain sensitive information from kernel memory via a crafted iso9660 image (bnc#912654).

CVE-2014-9420: The rock_continue function in fs/isofs/rock.c in the Linux kernel did not restrict the number of Rock Ridge continuation entries, which allowed local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image (bnc#911325).

CVE-2014-5471: Stack consumption vulnerability in the parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel allowed local users to cause a denial of service (uncontrolled recursion, and system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that has a CL entry (bnc#892490).

CVE-2014-5472: The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel allowed local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a self-referential CL entry (bnc#892490).

CVE-2014-3917: kernel/auditsc.c in the Linux kernel, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allowed local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number (bnc#880484).

CVE-2014-4652: 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 allowed local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (bnc#883795).

CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allowed 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 (bnc#883795).

CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not properly maintain the user_ctl_count value, which allowed 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 (bnc#883795).

CVE-2014-4653: sound/core/control.c in the ALSA control implementation in the Linux kernel did not ensure possession of a read/write lock, which allowed local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (bnc#883795).

CVE-2014-4656: Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed 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 (bnc#883795).

The update package also includes non-security fixes. See advisory for details.
