ruby: OpenSSL::X509:: Name equality check does not work correctly

An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one...

Authentication Bypass

openssl is vulnerable to an authentication bypass. The library does not properly compare OpenSSL::X509::Name objects, leading to non-equal objects to be returned as equal. This can allow a malicious user to pass a spoofed certificate to the system during the authentication process...

USN-3813-1: pyOpenSSL vulnerabilities

It was discovered that pyOpenSSL incorrectly handled memory when handling X509 objects. A remote attacker could use this issue to cause pyOpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2018-1000807 It was discovered that pyOpenSSL incorrectly handled...

Code injection

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-2018-16149

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

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-2018-16150

In axTLS 2.1.3 and earlier, the PKCS#1 v1.5 signature verification in sig_verify() fails to reject excess data after the hash, enabling signature forgery when small public exponents are used. This can lead to impersonation via forged X.509 certificates. This CVE-2018-16150 is a variant of CVE-200...

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...

CVE-2018-16149: Improper Verification of Cryptographic Signature

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-2018-16150: Improper Verification of Cryptographic Signature

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...

F5 Networks BIG-IP : IP Intelligence Feed List vulnerability (K11464209)

The version of F5 Networks BIG-IP installed on the remote host is prior to 11.5.6 / 11.6.3 / 12.1.2 HF1 / 13.0.0. It is, therefore, affected by a vulnerability as referenced in the K11464209 advisory. - X509 certificate verification was not correctly implemented in the IP Intelligence Subscriptio...

F5 Networks BIG-IP : BIG-IP AFM vulnerability (K20682450)

X509 certificate verification was not correctly implementedin the early access 'user id' feature in the BIG-IP Advanced Firewall Manager, and thus did not properly validate the remote server's identity on certain versions of BIG-IP. CVE-2017-6142 Impact In affected BIG-IP AFM versions, the system...
