Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Perl versions prior to 5.26.2

Description The issue is related to a heap-based buffer overflow error in the pack function of the Perl interpreter. This error occurs when handling a large number of elements, leading to a potential overflow of dynamic memory. The exploitation of this issue could allow a remote attacker to execute arbitrary code.

Recommendations For versions prior to 5.26.2, update to version 5.26.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the pack function when handling large item counts until a patch is applied.
