Name of the Vulnerable Software and Affected Versions
wolfSSL version 4.1.0
Description
The issue is related to a one-byte heap-based buffer over-read in the DecodeCertExtensions function located in wolfcrypt/src/asn.c. This occurs because the reading of the ASN BOOLEAN byte is mishandled for a crafted DER certificate in the GetLength ex function.
Recommendations
For wolfSSL version 4.1.0, consider updating to a newer version that addresses this issue, as the current version has a heap-based buffer over-read that could be exploited. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
