CVE-2016-1000030 medium priority: Ubuntu including 1 source packages (pidgin), 5 status rows across 5 suites (precise, trusty, upstream, wily, xenial): not-affected 4, released 1.
Pidgin version <2.11.0 contains a vulnerability in X.509 Certificates imports specifically due to improper check of return values from gnutls_x509_crt_init() and gnutls_x509_crt_import() that can result in code execution. This attack appear to be exploitable via custom X.509 certificate from another client. This vulnerability appears to have been fixed in 2.11.0.
