httplib2: httplib2: Denial of Service via unbounded decompression of HTTP response bodies

A flaw was found in httplib2, a Python HTTP client library. This vulnerability allows a malicious or compromised HTTP server to send a small compressed data payload that, when decompressed by httplib2, expands to an extremely large size in memory. This unbounded decompression can lead to a Denial...
