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 obtain sensitive information via a crafted certificate.

CVE-2014-3694 [MEDIUM] CWE-295 pidgin: SSL/TLS plug-ins failed to check Basic Constraints
pidgin: SSL/TLS plug-ins failed to check Basic Constraints
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 obtain sensitive information via a crafted certificate.
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.

CVE-2014-3694 [MEDIUM] CVE-2014-3694 pidgin: SSL/TLS plug-ins failed to check Basic Constraints
CVE-2014-3694 pidgin: SSL/TLS plug-ins failed to check Basic Constraints
It was reported that the SSL/TLS plug-ins failed to check that the Basic Constraints extension allowed intermediate certificates to act as Certificate Authorities (CAs). An attacker could use this flaw to create a fake certificate that Pidgin would trust, which could be used for man-in-the-middle attacks.
This is the same situation as described in http://www.thoughtcrime.org/ie-ssl-chain.txt
