Technical Summary
This advisory covers two security flaws in the python-tornado package maintained by Red Hat. CVE-2026-31958 is a denial of service vulnerability triggered by processing large multipart bodies, potentially allowing resource exhaustion. CVE-2026-35536 involves cookie attribute injection caused by improper handling of cookie arguments, which could lead to security issues related to cookie management. Red Hat has released updated python-tornado packages for multiple architectures and variants of Red Hat Enterprise Linux 9.6 Extended Update Support to address these vulnerabilities.
Potential Impact
The denial of service vulnerability (CVE-2026-31958) could allow an attacker to disrupt service availability by sending large multipart bodies. The cookie attribute injection vulnerability (CVE-2026-35536) could allow an attacker to inject or manipulate cookie attributes, potentially affecting session security or user authentication mechanisms. Both vulnerabilities are rated as moderate impact by Red Hat.
Mitigation Recommendations
Red Hat has released updated python-tornado packages that fix these vulnerabilities. Users of affected Red Hat Enterprise Linux 9.6 Extended Update Support versions should apply the provided updates as described in the Red Hat advisory RHSA-2026:20572.
