CyberRota Analysis
AI-GeneratedThe vulnerability affects libsoup versions 3.0 to 3.7.0, specifically within its HTTP/2 connection tracking framework, where improper handling of the "Additional Debug Data" in a GOAWAY frame can lead to a heap buffer over-read. This flaw allows a remote, unauthenticated attacker to exploit the library, potentially causing application crashes and a denial of service (DoS), as well as exposing sensitive memory fragments. Organizations using affected libsoup versions should prioritize patching to mitigate these risks.
Original NVD Description
A heap buffer over-read vulnerability was discovered in libsoup's (versions: libsoup 3.0 to 3.7.0) HTTP/2 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminated C-string. Because the parser lacks strict length-boundary verification before reading this data, a remote, unauthenticated attacker can intentionally send a malformed GOAWAY frame missing the appropriate null delimiter. This causes the library to read past the end of the allocated buffer, triggering an application crash that results in a denial of service (DoS), or potentially exposing fragments of memory contents.
