CVE-2018-16253 (GCVE-0-2018-16253)

Vulnerability from cvelistv5 – Published: 2018-11-07 20:00 – Updated: 2024-08-05 10:17
VLAI
Summary
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification does not properly verify the ASN.1 metadata. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation through fake X.509 certificates. This is an even more permissive variant of CVE-2006-4790 and CVE-2014-1568.
