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. Condición de carrera en la funcionalidad del manejador de tlv en la función snd_ctl_elem_user_tlv en sound/core/control.c en la implementación del control ALSA en el kernel de Linux anterior a 3.15.2 permite a usuarios locales obtener información sensible de la memoria del kernel mediante el aprovechamiento del acceso a /dev/snd/controlCX An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=07f4d9d74a04aa7c72c5dae0ef97565f28f17b92 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://rhn.redhat.com/errata/RHSA-2014-1083.html http://rhn.redhat.com/errata/RHSA-2015-1272.html http://secunia.com/advisories/59434 http://secunia.com/advisories/59777 http://secunia.com/advisories/60545 http://secunia.com/advisories/60564 http://www.kernel.org/pub/linux/kernel/v3.x/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

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. sound/core/control.c de la implementación del control de ALSA en el kernel de Linux anterior a 3.15.2 no asegura la posesión de un bloqueo de lectura/escritura, lo que permite a usuarios locales provocar una denegación de servicio (uso después de liberación) y obtener información sensible de la memoria del kernel al aprovechar el acceso a /dev/snd/controlICX.

Integer overflow in the LZ4 algorithm implementation, as used in Yann Collet LZ4 before r118 and in the lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit platforms might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run that would be improperly handled by programs not complying with an API limitation, a different vulnerability than CVE-2014-4715.

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.

NOTA: el autor de los algoritmos LZO algorithms dice que 'el kernel de Linux *no* está afectado; sensacionalismo periodístico.' An integer overflow flaw was found in the way the lzo1x_decompress_safe() function of the Linux kernel's LZO implementation processed Literal Runs. A local attacker could, in extremely rare cases, use this flaw to crash the system or, potentially, escalate their privileges on the system. • http://blog.securitymouse.com/2014/06/raising-lazarus-20-year-old-bug-that.html http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=206a81c18401c0cde6e579164f752c4b147324ce http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-0062.html http://secunia.com/advisori • CWE-190: Integer Overflow or Wraparound •

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.
