pidgin: SSL/TLS plug-ins failed to check Basic Constraints

It was found that Pidgin's SSL/TLS plug-ins had a flaw in the certificate validation functionality. An attacker could use this flaw to create a fake certificate, that Pidgin would trust, which could be used to conduct man-in-the-middle attacks against Pidgin...

The vulnerability of the OpenSSL library, which allows a hacker to bypass the standard procedures for verifying certificate chains

The vulnerability of the X509verifycert function in the OpenSSL library is related to insufficient handling of the X.509 Basic Constraints cA value during the identification of an alternative certificate chain. Exploiting this vulnerability allows a malicious actor to bypass the standard...

The X509verifycert function in crypto/x509/x509vfy.c in OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, and 1.0.2c does not properly process X.509 Basic Constraints cA values during identification of alternative certificate chains, which allows remote attackers to spoof a Certification Authority role and trigger...

smack: incorrect X.509 certificate validation

It was found that the ServerTrustManager in the Smack XMPP API did not verify basicConstraints and nameConstraints in X.509 certificate chains. A man-in-the-middle attacker could use this flaw to spoof servers and obtain sensitive information...

DEBIAN-CVE-2014-3694

The 1 bundled GnuTLS SSL/TLS plugin and the 2 bundled OpenSSL SSL/TLS plugin in libpurple in Pidgin before 2.10.10 do not properly consider the Basic Constraints extension during verification of X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and...

MGASA-2014-0425 Updated pidgin packages fix security vulnerabilities

In Pidgin before 2.10.10, both of libpurple's bundled SSL/TLS plugins one for GnuTLS and one for NSS failed to check that the Basic Constraints extension allowed intermediate certificates to act as CAs. This allowed anyone with any valid certificate to create a fake certificate for any arbitrary...

SSL Certificate Fails to Adhere to Basic Constraints / Key Usage Extensions

An X.509 certificate sent by the remote host contains one or more violations of the restrictions imposed on it by RFC 5280. This means that either a root or intermediate Certificate Authority signed a certificate incorrectly. Certificates that fail to adhere to the restrictions in their extension...
