CVE-2018-16253

CVE-2018-16253 describes a flaw in axTLS 2.1.3 and earlier where PKCS#1 v1.5 signature verification in sig_verify() of x509.c does not properly verify ASN.1 metadata, enabling a remote attacker to forge signatures under small public exponents and impersonate via fake X.509 certificates. The issue...

CVE-2018-16149

In sigverify in x509.c in axTLS version 2.1.3 and before, the PKCS1 v1.5 signature verification blindly trusts the declared lengths in the ASN.1 structure. Consequently, when small public exponents are being used, a remote attacker can generate purposefully crafted signatures and put them on X.50...

openssl: Handling of crafted recursive ASN.1 structures can cause a stack overflow and resulting denial of service

Constructed ASN.1 types with a recursive definition such as can be found in PKCS7 could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so...
