paul Posted April 17, 2010 Report Share Posted April 17, 2010 Multiple vulnerabilities has been found and corrected in irssi: Irssi before 0.8.15, when SSL is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) field or a Subject Alternative Name field of the X.509 certificate, which allows man-in-the-middle attackers to spoof IRC servers via an arbitrary certificate (CVE-2010-1155). core/nicklist.c in Irssi before 0.8.15 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors related to an attempted fuzzy nick match at the instant that a victim leaves a channel (CVE-2010-1156). Additionally the updated packages disables the SSLv2 protocol and enables the SSLv3 and TLSv1 protocols for added security. The updated packages have been patched to correct these issues.
