Description

A flaw was found in Storable for Perl. A remote attacker can exploit a vulnerability in the `retrieve_hook` function by crafting malicious data. This flaw occurs because the function incorrectly handles the length of class names, storing it as a signed integer but processing it as unsigned during read operations. Successful exploitation leads to a stack overflow, which can cause a denial of service.
