    CVE ID         : CVE-2025-49506 CVE-2026-32327 CVE-2026-34501 CVE-2026-34502
    Debian Bug     : 1143837

    Several vulnerabilities were discovered in apr-util, the Apache Portable
    Runtime Utility library, which could result in denial of service or
    potentially the execution of arbitrary code.

    For the stable distribution (trixie), these problems have been fixed in
    version 1.6.3-3+deb13u1.

    We recommend that you upgrade your apr-util packages.

    For the detailed security status of apr-util please refer to its
    security tracker page at:
    https://security-tracker.debian.org/tracker/apr-util
