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
This advisory covers two security issues in the python-tornado package for Red Hat Enterprise Linux 10.0 EUS. CVE-2026-31958 is a denial of service vulnerability triggered by large multipart bodies, classified under CWE-770 (Allocation of Resources Without Limits or Throttling). CVE-2026-35536 involves cookie attribute injection due to improper handling of cookie arguments, related to CWE-88 (Argument Injection or Modification). Red Hat has released updated python-tornado packages (version 6.4.2-1.el10_0.2) to address these issues. The advisory does not provide CVSS scores but rates the impact as moderate. The update is available for multiple architectures including x86_64, s390x, ppc64le, and aarch64.
Potential Impact
The denial of service vulnerability (CVE-2026-31958) could allow an attacker to disrupt service by sending large multipart bodies, potentially exhausting resources. The cookie attribute injection vulnerability (CVE-2026-35536) could allow manipulation of cookie attributes, which may affect security controls relying on cookie integrity. Both issues have moderate severity as rated by Red Hat. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated python-tornado packages (version 6.4.2-1.el10_0.2) for Red Hat Enterprise Linux 10.0 Extended Update Support to address these vulnerabilities. Users should apply the official updates as described in the Red Hat advisory (https://access.redhat.com/articles/11258). Since this is an official fix, applying the update fully mitigates the issues. No additional mitigation steps are indicated by the vendor.
