Rob Flynn » Gaim : Security Vulnerabilities, CVEs, (Denial of service) CVSS score >= 6

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.

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.

Multiple buffer overflows in Gaim before 0.82 allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) Rich Text Format (RTF) messages, (2) a long hostname for the local system as obtained from DNS, or (3) a long URL that is not properly handled by the URL decoder.

Integer overflow in Gaim before 0.82 allows remote attackers to cause a denial of service and possibly execute arbitrary code via the size variable in Groupware server messages.

Buffer overflow in the MSN protocol plugins (1) object.c and (2) slp.c for Gaim before 0.82 allows remote attackers to cause a denial of service and possibly execute arbitrary code via MSNSLP protocol messages that are not properly handled in a strncpy call.

Integer overflow in Gaim 0.74 and earlier, and Ultramagnetic before 0.81, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a directIM packet that triggers a heap-based buffer overflow.

Buffer overflow in the Extract Info Field Function for (1) MSN and (2) YMSG protocol handlers in Gaim 0.74 and earlier, and Ultramagnetic before 0.81, allows remote attackers to cause a denial of service and possibly execute arbitrary code.

Multiple buffer overflows in Gaim 0.75 and earlier, and Ultramagnetic before 0.81, allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) cookies in a Yahoo web connection, (2) a long name parameter in the Yahoo login web page, (3) a long value parameter in the Yahoo login page, (4) a YMSG packet, (5) the URL parser, and (6) HTTP proxy connect.

Buffer overflow in Gaim 0.10.3 and earlier using the OSCAR protocol allows remote attackers to conduct a denial of service and possibly execute arbitrary commands via a long HTML tag.
