CVE-2023-45853: MiniZip and pyminizip may allow attackers to crash systems with long file names

Summary

MiniZip and a version of pyminizip that bundles an affected zlib library may be vulnerable to a crash if an attacker uses a very long file name, comment, or extra field. This could potentially allow an attacker to disrupt normal system operations. If you use either of these tools, it's a good idea to update to a newer version that fixes this issue.

What to do

No fix is available yet. Check with your software vendor for updates.

Original description

MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_64 via a long filename, comment, or extra field. NOTE: MiniZip is not a supported part of the zlib product. NOTE: pyminizip through 0.2.6 is also vulnerable because it bundles an affected zlib version, and exposes the applicable MiniZip code through its compress API.
