CVE-2018-1842

The CVE-2018-1842 issue affects IBM Cognos Analytics 11 Configuration tool. The root cause is a bypass of OIDC namespace signature verification on the id_token under certain conditions. This leads to a potential security impact where token validation may be weakened, allowing an attacker to explo...

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...

CVE-2018-16253

In sigverify in x509.c in axTLS version 2.1.3 and before, the PKCS1 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...

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

axTLS vulnerability CVE-2018-16149 affects version 2.1.3 and earlier, where sig_verify() in x509.c blindly trusts ASN.1 declared lengths in PKCS#1 v1.5 signatures. When small public exponents are used, a remote attacker can create crafted signatures on X.509 certificates that trigger illegal memo...

bouncycastle: DSA does not fully validate ASN.1 encoding during signature verification allowing for injection of unsigned data

In Bouncy Castle JCE Provider version 1.55 and earlier the DSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of...
