    Package        : perl     CVE ID         : CVE-2024-56406

    Nathan Mills discovered a heap-based buffer overflow vulnerability in     the implementation of the Perl programming language when transliterating     non-ASCII bytes with tr///, which may result in denial of service, or     potentially the execution of arbitrary code.

    For the stable distribution (bookworm), this problem has been fixed in     version 5.36.0-7+deb12u2.

    We recommend that you upgrade your perl packages.
