CVE-2017-20230 not yet assigned priority: Debian including 1 source packages (perl), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
