Package : nginx CVE ID : CVE-2026-42055 CVE-2026-48142 Debian Bug : 1140359 1140361

Multiple vulnerabilities were discoverd in Nginx, a high-performance web and reverse proxy server, which could result in remote code execution, denial of service or memory disclosure.

For the stable distribution (trixie), these problems have been fixed in version 1.26.3-3+deb13u7.

We recommend that you upgrade your nginx packages.
