Gaim before 1.3.1 allows remote attackers to cause a denial of service (crash) via a malformed MSN message that leads to a memory allocation of a large size, possibly due to an integer signedness error.
Stack-based buffer overflow in the URL parsing function in Gaim before 1.3.0 allows remote attackers to execute arbitrary code via an instant message (IM) with a large URL.
The HTML parsing functions in Gaim before 1.1.4 allow remote attackers to cause a denial of service (application crash) via malformed HTML that causes "an invalid memory access," a different vulnerability than CVE-2005-0473.

The IRC protocol plugin in Gaim 1.2.0, and possibly earlier versions, allows (1) remote attackers to inject arbitrary Gaim markup via irc_msg_kick, irc_msg_mode, irc_msg_part, irc_msg_quit, (2) remote attackers to inject arbitrary Pango markup and pop up empty dialog boxes via irc_msg_invite, or (3) malicious IRC servers to cause a denial of service (application crash) by injecting certain Pango markup into irc_msg_badmode, irc_msg_banned, irc_msg_unknown, irc_msg_nochan functions.
