    Package        : libdbi-perl
    CVE ID         : CVE-2026-9698 CVE-2026-10879

    Two vulnerabilities were discovered in libdbi-perl, a Perl framework
    that provides a common interface to access various backend databases in
    a uniform manner, which may result in denial of service, or potentially
    the execution of arbitrary code.

    For the oldstable distribution (bookworm), these problems have been fixed
    in version 1.643-4+deb12u1.

    For the stable distribution (trixie), these problems have been fixed in
    version 1.647-1+deb13u1.

    We recommend that you upgrade your libdbi-perl packages.

    For the detailed security status of libdbi-perl please refer to its
    security tracker page at:
