Debian DLA-3043-1 : pidgin - LTS security update

medium Nessus Plugin ID 161907

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-3043 advisory.

- 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. (CVE-2022-26491)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the pidgin packages.

For Debian 9 stretch, this problem has been fixed in version 2.12.0-1+deb9u1.
