Last modified
CVE-2017-20230 is a critical-severity vulnerability rated 10/10 on the CVSS scale. 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.. EPSS estimates a 0.64% chance of exploitation in the next 30 days.
