    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 oldstable distribution (bookworm), a subset of these problems     have been fixed in version 4.0.17-0+deb12u3.

    For the stable distribution (trixie), these problems have been fixed in     version 4.4.15-0+deb13u1.

    We recommend that you upgrade your wireshark packages.
