CVE-2017-20230 (GCVE-0-2017-20230)

Vulnerability from cvelistv5 – Published: 2026-04-21 15:26 – Updated: 2026-04-21 18:22

Title

Storable versions before 3.05 for Perl has a stack overflow

Summary

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.

Severity

GHSA-6R7M-2WH8-438W

Vulnerability from github – Published: 2026-04-21 18:31 – Updated: 2026-04-21 21:31

Details

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.

Severity

10.0 (Critical)

Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update

Severity

Moderate

Scope

1 vulnerability in this advisory, including CVE-2017-20230.

CVE-2017-20230

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.
