Red Hat Security Advisory: python-tornado security update
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * tornado-python: Tornado: Denial of Service via large multipart bodies (CVE-2026-31958) * tornado: Tornado: Cookie attribute injection due to improper handling of cookie arguments (CVE-2026-35536) 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 pcs packages, which provide command-line configuration for Pacemaker and Corosync utilities in Red Hat Enterprise Linux 8, were found vulnerable due to a denial of service issue in the tornado-python component. Specifically, Tornado can be overwhelmed by large multipart bodies, leading to denial of service (CVE-2026-31958). Red Hat has issued a security advisory (RHSA-2026:8093) with updated pcs packages to address this vulnerability. The advisory covers multiple architectures and product variants of Red Hat Enterprise Linux 8 High Availability and Resilient Storage. No CVSS score is provided, but the issue is rated moderate in severity.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to cause a denial of service condition in the pcs service by sending large multipart bodies to the Tornado framework component. This could disrupt cluster management operations relying on pcs, potentially affecting high availability and resilient storage configurations. There is no indication of code execution or data breach from the advisory.
Mitigation Recommendations
Red Hat has released updated pcs packages that fix this vulnerability. Users of affected Red Hat Enterprise Linux 8 High Availability and Resilient Storage variants should apply the updates as described in Red Hat advisory RHSA-2026:8093 and the referenced article https://access.redhat.com/articles/11258. Since this is an official fix, applying the update fully mitigates the issue.
