CVE-2014-4611: Integer Overflow
First published: Tue Jun 24 2014(Updated: )
Don A. Bailey of Lab Mouse Security reported an integer overflow issue in various implementations of LZO (Lempel–Ziv–Oberhumer) and LZ4 compression algorithms. The issue is in the handling of "literal runs" during decompression, and can lead to application crash and, possibly, code execution. This bug is for LZ4 and LZ4 copy embedded in the Linux kernel (as of version 3.11). This issue can not be triggered on 64bit systems today, as it would require input of the size that is beyond capabilities of modern computers. On 32bit systems, this can only affect applications using sufficiently large decompression blocks (16mb+).
