NVD Description

Note: Versions mentioned in the description apply only to the upstream lz4 package and not the lz4 package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

There's a flaw in lz4. An attacker who submits a crafted file to an application linked with lz4 may be able to trigger an integer overflow, leading to calling of memmove() on a negative size argument, causing an out-of-bounds write and/or a crash. The greatest impact of this flaw is to availability, with some potential impact to confidentiality and integrity as well.
