Security Fix(es): * libsoup: Heap buffer over-read in `skip_insignificant_space` when sniffing content (CVE-2025-2784) * libsoup: Denial of Service attack to websocket server (CVE-2025-32049) * libsoup: OOB Read on libsoup through function "soup_multipart_new_from_message" in soup-multipart.c leads to crash or exit of process (CVE-2025-32914) * libsoup: Integer Underflow in soup_multipart_new_from_message() Leading to Denial of Service in libsoup (CVE-2025-4948) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The libsoup library for GNOME contains several security flaws: a heap buffer over-read in the skip_insignificant_space function (CVE-2025-2784), a denial of service vulnerability affecting the websocket server (CVE-2025-32049), an out-of-bounds read in soup_multipart_new_from_message causing crashes (CVE-2025-32914), and an integer underflow in the same function leading to denial of service (CVE-2025-4948). These vulnerabilities can cause crashes or denial of service conditions. Red Hat has issued an update for Red Hat Enterprise Linux 8.8 Extended Update Support to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities can lead to denial of service conditions or application crashes in software using libsoup. There is no indication of code execution or data disclosure impacts. The vulnerabilities affect HTTP client and server functionality, including websocket servers and multipart message processing.
Mitigation Recommendations
Red Hat has released an important security update for libsoup in Red Hat Enterprise Linux 8.8 Extended Update Support. Users should apply the update as described in the Red Hat advisory RHSA-2025:8252 to remediate these vulnerabilities. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor.
