CVE-2026-15714 (GCVE-0-2026-15714)

Vulnerability from cvelistv5 – Published: 2026-07-14 19:50 – Updated: 2026-07-15 14:09

Title

Libsoup: soupmultipartinputstream: libsoup: out-of-bounds read in soup_multipart_input_stream_read_headers via an oversized multipart boundary string

Summary

An out-of-bounds read vulnerability was found in libsoup's multipart processing subsystem. The flaw exists in the soup_multipart_input_stream_read_headers() function inside soup-multipart-input-stream.c, which does not adequately restrict or validate the size of incoming multipart boundary strings. When processing a crafted HTTP response containing a malformed or oversized boundary parameter, the internal stream reader reads past the allocated buffer bounds. A remote, unauthenticated attacker can exploit this behavior to cause a service denial (DoS) through application failure or potentially read fragments of unauthorized memory metadata.

Severity

6.5 (Medium)

  "details": "An out-of-bounds read vulnerability was found in libsoup\u0027s multipart processing subsystem. The flaw exists in the soup_multipart_input_stream_read_headers() function inside soup-multipart-input-stream.c, which does not adequately restrict or validate the size of incoming multipart boundary strings. When processing a crafted HTTP response containing a malformed or oversized boundary parameter, the internal stream reader reads past the allocated buffer bounds. A remote, unauthenticated attacker can exploit this behavior to cause a service denial (DoS) through application failure or potentially read fragments of unauthorized memory metadata.",
