OESA-2025-1473 (CVE-2024-56406)

Vulnerability from osv_openeuler – Published: 2025-05-09 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

perl security update

Details

Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large scale development projects.

Security Fix(es):

A heap buffer overflow vulnerability was discovered in Perl.

Release branches 5.34, 5.36, 5.38 and 5.40 are affected, including development versions from 5.33.1 through 5.41.10.

When there are non-ASCII bytes in the left-hand-side of the tr operator, S_do_trans_invmap can overflow the destination pointer d.

$ perl -e '$_ = "\x{FF}" x 1000000; tr/\xFF/\x{100}/;' Segmentation fault (core dumped)

It is believed that this vulnerability can enable Denial of Service and possibly Code Execution attacks on platforms that lack sufficient defenses.(CVE-2024-56406)

Severity

9.8 (Critical)
