telepathy-idle before 0.1.15 does not verify (1) that the issuer is a trusted CA, (2) that the server hostname matches a domain name in the subject's Common Name (CN), or (3) the expiration date of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Changes in telepathy-idle :

  - Add telepathy-idle-require-tls-validation.patch     (bnc#817120, CVE-2007-6746). This fixes flaws in the SSL     certificate validation.

Telepathy-idle did not check SSL certificates. CVE-2007-6746 was assigned to this issue.

It was discovered that telepathy-idle did not perform any server certificate validation when using SSL connections. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to alter or compromise confidential information.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This release validate TLS certificates properly, preventing man-in-the-middle attacks.

This will be a regression for users of IRC-over-SSL servers/proxies that do not have a certificate trusted by system-wide CA configuration; they will no longer be able to connect. If someone implements fd.o #57130, that will provide the ability for those users to approve additional certificates.
