CyberRota Analysis
AI-GeneratedA heap buffer overflow vulnerability exists in the PJLIB-UTIL HTTP client, affecting applications that handle complete HTTP response bodies without incremental reading. This flaw can be exploited by a malicious or man-in-the-middle server to corrupt memory or cause application crashes, posing a significant risk to affected systems. Developers and organizations utilizing the PJLIB-UTIL HTTP client should prioritize applying the patch to mitigate potential exploitation.

Original NVD Description
PJSIP is a free and open source multimedia communication library written in C. Prior to commit 8d5956a, a heap buffer overflow exists in the PJLIB-UTIL HTTP client (http_client.c) when buffering an HTTP response body. This affects applications that use the PJLIB-UTIL HTTP client to receive a whole response body at once (a completion callback with no incremental on_data_read callback). When growing the response buffer, an incorrect size calculation based on the server-supplied Content-Length can leave the buffer too small, causing response data to be written past the end of the allocation. A malicious or man-in-the-middle HTTP server can trigger this with a crafted response; impact may range from unexpected application termination to memory corruption. Applications that consume the response incrementally (via on_data_read), or that only connect to trusted servers, are not affected. This issue has been patched via commit 8d5956a.
