lz4: memory corruption due to an integer overflow bug caused by memmove argument

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...
