CVE-2024-56406 (GCVE-0-2024-56406)

Vulnerability from cvelistv5 – Published: 2025-04-13 13:16 – Updated: 2025-10-16 14:04

Title

Perl is vulnerable to a heap buffer overflow when transliterating non-ASCII bytes

Summary

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.

Severity ?

8.4 (High)
