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.

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.

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. La función snd_ctl_elem_add en sound/core/control.c en la implementación del control ALSA en el kernel de Linux anterior a 3.15.2 no gestiona debidamente el valor user_ctl_count, lo que permite a usuarios locales causar una denegación de servicio (desbordamiento de enteros y evadir el limite) mediante el aprovechamiento de acceso /dev/snd/controlCX para un numero largo de llamadas SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl.

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. NOTE: the author of the LZO algorithms says "the Linux kernel is *not* affected; media hype. ** DISPUTADA ** Múltiples desbordamientos de enteros en la función lzo1x_decompress_safe en lib/lzo/lzo1x_decompress_safe.c en el descompresor LZO en el kernel de Linux anterior a 3.15.2 permiten a atacantes dependientes de contexto causar una denegación de servicio (corrupción de memoria) a través de un 'Literal Run' manipulado. 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.
