Descriptions
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. A local attacker could, in extremely rare cases, use this flaw to crash the system or, potentially, escalate their privileges on the system.
