"The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare
ALMALINUX9.2:CLSA-2023:1702495051 advisory.

  - A vulnerability was found in perl 5.30.0 through 5.38.0. This issue occurs when a crafted regular
    expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap
    allocated buffer. (CVE-2023-47038)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
