A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available from the CVE link in the References section. Description bzip2 is a freely available, high-quality data compressor. It provides both standalone compression and decompression utilities, as well as a shared library for use with other programs. An integer overflow flaw was discovered in the bzip2 decompression routine.

All running applications using the libbz2 library must be restarted for the update to take effect.
