An issue was discovered in Pidgin before 2.14.9. A remote attacker who can spoof DNS responses can redirect a client connection to a malicious server. The client will perform TLS certificate verification of the malicious domain name instead of the original XMPP service domain, allowing the attacker to take over control over the XMPP connection and to obtain user credentials and all communication content. This is similar to CVE-2022-24968.

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.

The Mxit protocol uses weak encryption when encrypting user passwords, which might allow attackers to (1) decrypt hashed passwords by leveraging knowledge of client registration codes or (2) gain login access by eavesdropping on login messages and re-using the hashed passwords.
