• Exploited in the wild: not listed in CISA KEV
• EPSS: 2.6% probability of exploitation in the next 30 days

Description

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.

Affected products

• Debian Linux: 9.0
• Pidgin: before 2.14.9 — fixed in 2.14.9

How to fix

Upgrade to a fixed version: Pidgin 2.14.9. Check the vendor advisory for mitigations.
