RUSTSEC-2023-0004 (CVE-2023-22895)

Vulnerability from osv_rustsec – Published: 2023-01-09 12:00 – Updated: 2023-02-04 13:29 – Source website

Summary

bzip2 Denial of Service (DoS)

Details

Working with specific payloads can cause a Denial of Service (DoS) vector.

Both Decompress and Compress implementations can enter into infinite loops given specific payloads entered that trigger it.

The issue is described in great detail in the bzip2 repository issue.

Thanks to bjrjk for finding and providing the patch for the issue and the maintainer responsibly responding to release a fix quickly.

Users who use the crate with untrusted data should update the bzip2 to 0.4.4.
