Description OSIDB Bzimport 2026-04-21 16:01:22 UTC 
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.
