CVE-2014-4611

Priority
Medium
Description
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.
Ubuntu-Description
Don Bailey and Ludvig Strigeus discovered an integer overflow in the Linux
kernel's implementation of the LZ4 decompression algorithm, when used by
code not complying with API limitations. An attacker could exploit this
flaw to cause a denial of service (memory corruption) or possibly other
unspecified impact.
