CVE-2019-10013: Buffer Copy without Checking Size of Input

The asn1signature function in asn1.c in Cameron Hamilton-Rich axTLS through 2.1.5 has a Buffer Overflow that allows remote attackers to cause a denial of service memory and CPU consumption via a crafted certificate in the TLS certificate handshake message, because the result of getasn1length is n...

CVE-2019-8981

CVE-2019-8981 affects the axTLS library (tls1.c) prior to version 2.1.5. The root cause is a mismanagement of the need_bytes value, leading to a buffer overflow when processing crafted TLS packets. Documented impact is a buffer overflow; exploitation details are not provided in the connected docu...

CVE-2018-16150

In sigverify in x509.c in axTLS version 2.1.3 and before, the PKCS1 v1.5 signature verification does not reject excess data after the hash value. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation through fake X.509...

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...
