  script_tag(name:"insight", value:"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.

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

We recommend that you upgrade your pidgin packages.

For the detailed security status of pidgin please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
