Amazon Linux 2 : pidgin (ALAS-2023-2115)

medium Nessus Plugin ID 178558

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of pidgin installed on the remote host is prior to 2.10.11-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2115 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

Run 'yum update pidgin' to update your system.
