    Multiple vulnerabilities have been discocvered in Wireshark, a network
    protocol analyzer which could result in denial of service or the
    execution of arbitrary code.

    For the stable distribution (trixie), these problems have been fixed in
    version 4.4.18-0+deb13u1.

    We recommend that you upgrade your wireshark packages.

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