CVE-2024-5991 (GCVE-0-2024-5991)

Vulnerability from cvelistv5

Published

2024-08-27 18:33

Modified

2024-08-27 20:06

Severity ?

10.0 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

CWE

CWE-125 - Out-of-bounds Read

Summary

In function MatchDomainName(), input param str is treated as a NULL terminated string despite being user provided and unchecked. Specifically, the function X509_check_host() takes in a pointer and length to check against, with no requirements that it be NULL terminated. If a caller was attempting to do a name check on a non-NULL terminated buffer, the code would read beyond the bounds of the input array until it found a NULL terminator.This issue affects wolfSSL: through 5.7.0.
