The libsoup library used in GNOME provides HTTP client and server functionality and has multiple security flaws: CVE-2025-2784 is a heap buffer over-read in the skip_insignificant_space function during content sniffing; CVE-2025-32049 allows denial of service attacks against the websocket server; CVE-2025-32914 is an out-of-bounds read in soup_multipart_new_from_message causing crashes or process exit; CVE-2025-4948 is an integer underflow in the same function leading to denial of service. Red Hat has released updated packages for Red Hat Enterprise Linux 8.4 to address these vulnerabilities as detailed in advisory RHSA-2025:8663.

Successful exploitation of these vulnerabilities could lead to denial of service conditions by crashing or exiting the affected process or causing resource exhaustion. The heap buffer over-read and out-of-bounds read could potentially lead to application instability or crashes. There is no indication of remote code execution or data disclosure in the advisory. The vulnerabilities affect the libsoup library used in HTTP client and server contexts, potentially impacting applications relying on this library.

Red Hat has released updated libsoup packages for Red Hat Enterprise Linux 8.4 that address these vulnerabilities. Users should apply the security update as described in Red Hat advisory RHSA-2025:8663 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.
