    CVE-2013-7449

    Published: 21 Apr 2016Last Modified: 10 Apr 2026

    Summary:

    Details: The ssl_do_connect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
