Descriptions

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.

(1) El plugin bundled GnuTLS SSL/TLS y (2) el plugin bundled OpenSSL SSL/TLS en libpurple en Pidgin anterior a 2.10.10 no consideran debidamente la extensión Basic Constraints durante la verificación de los certificados X.509 de los servidores SSL, lo que permite a atacantes man-in-the-middle suplantar servidores y obtener información sensible a través de un certificado manipulado.

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.
