CVE-2019-16748

CVE-2019-16748 affects wolfSSL (through 4.1.0) due to a missing sanity check of memory accesses during ASN.1 certificate parsing in the handshake. The issue is a one-byte heap-based buffer over-read in CheckCertSignature_ex (wolfcrypt/src/asn.c). This can lead to a severe impact as reflected by C...

wolfSSL Buffer Over-Read Vulnerability

wolfSSL is a small, portable, embedded SSL/TLS library intended for use by embedded systems developers. A buffer over-read vulnerability exists in DecodeCertExtensions in wolfcrypt/src/asn.c in wolfSSL 4.1.0, which stems from an ASNBOOLEAN byte read handling error in GetLengthex, and can be...
