CVE-2021-3520 (GCVE-0-2021-3520)

Vulnerability from cvelistv5 – Published: 2021-06-02 12:32 – Updated: 2024-08-03 17:01

Summary

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.
