Multiple format string vulnerabilities in (1) _invitedToRoom: and (2) _invitedToDirectChat: in Colloquy 2.1 and earlier allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in the channel name of an INVITE request, related to the implementation of AlertSheet and AlertPanel in Apple AppKit.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
