Buffer overflow in the MSN protocol handler for gaim 0.79 to 1.0.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an "unexpected sequence of MSNSLP messages" that results in an unbounded copy operation that writes to the wrong buffer.

Gaim before 0.82 allows remote servers to cause a denial of service (application crash) via a long HTTP Content-Length header, which causes Gaim to abort when attempting to allocate memory.

The HTML parsing functions in Gaim before 1.1.3 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-2005-0208.

Gaim 1.1.3 on Windows systems allows remote attackers to cause a denial of service (client crash) via a file transfer in which the filename contains "(" or ")" (parenthesis) characters.

The gaim_markup_strip_html function in Gaim 1.2.0, and possibly earlier versions, allows remote attackers to cause a denial of service (application crash) via a string that contains malformed HTML, which causes an out-of-bounds read.

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.

Gaim 1.2.0 allows remote attackers to cause a denial of service (application crash) via a malformed file transfer request to a Jabber user, which leads to an out-of-bounds read.

Gaim before 1.3.1 allows remote attackers to cause a denial of service (application crash) via a Yahoo! message with non-ASCII characters in a file name.

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.
