Storable versions before 3.05 for Perl has a stack overflow. The retrieve_hook function stored the length of the class name into a signed integer but in read operations treated the length as unsigned. This allowed an attacker to craft data that could trigger the overflow.

The version of perl-Storable installed on the remote host is prior to 2.45-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3388 advisory.
