AI Analysis
Technical Summary
The libsoup library, used for HTTP client and server functionality in GNOME, contains two vulnerabilities: an integer overflow in cookie expiration date handling (CVE-2025-4945) and an out-of-bounds read in cookie date handling (CVE-2025-11021). These vulnerabilities could potentially lead to memory corruption or crashes when processing cookie expiration dates. Red Hat has released updated libsoup packages for Red Hat Enterprise Linux 8 to fix these issues. The advisory covers multiple architectures including x86_64, s390x, ppc64le, and aarch64. The update is classified as important by Red Hat Product Security. No CVSS score is provided in the advisory.
Potential Impact
The integer overflow and out-of-bounds read vulnerabilities in libsoup's cookie date handling may allow an attacker to cause memory corruption or application crashes in software using this library. This could impact applications relying on libsoup for HTTP communications, potentially leading to denial of service or other unintended behavior. The advisory does not specify exploitation in the wild or further impact details.
Mitigation Recommendations
Red Hat has released updated libsoup packages for Red Hat Enterprise Linux 8 that address these vulnerabilities. Users should apply the official Red Hat update as described in the advisory RHSA-2025:19714 and the referenced article https://access.redhat.com/articles/11258 to remediate these issues. The update is available for multiple architectures and extended life cycle versions. Patch status is confirmed as an official fix provided by Red Hat.
