CVE-2026-59939

CVE-2026-59939 · httplib2: Decompression Bomb Denial of Service via Unbounded gzip/deflate Response Handling

This page contains facts from public vulnerability sources. Check the original advisory before updating.

httplib2 is a comprehensive HTTP client library for Python. Prior to 0.32.0, httplib2 performs unbounded decompression of HTTP response bodies encoded with Content-Encoding: gzip or deflate in _decompressContent in httplib2/init.py, allowing a malicious or compromised HTTP server to return a small compressed payload that expands to an arbitrarily large size in memory and causes MemoryError or OOM-kill in the client process. This issue is fixed in version 0.32.0.
