Description

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.

Solution(s)

  • suse-upgrade-liblz4-1
  • suse-upgrade-liblz4-1-32bit
  • suse-upgrade-liblz4-devel
  • suse-upgrade-lz4
