NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup-3_0-0 package and not the libsoup-3_0-0 package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle (MITM) attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file body is being read asynchronously. This can lead to memory corruption, potentially resulting in information disclosure or arbitrary code execution.
