CVE-2014-4608

[John Johansen]

** DISPUTED ** 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."

Break-Fix: 64c70b1cf43de158282bc1675918d503e5b15cc1 72cf90124e87d975d0b2114d930808c58b4c05e4
