Heap-based buffer overflow in the Rendezvous / Extensible Messaging and Presence Protocol (XMPP) component (plugins\rendezvous.dll) for Cerulean Studios Trillian Pro before 3.1.5.1 allows remote attackers to execute arbitrary code via a message that triggers the overflow from expansion that occurs during encoding.

Multiple heap-based buffer overflows in the IRC component in Cerulean Studios Trillian Pro before 3.1.5.1 allow remote attackers to corrupt memory and possibly execute arbitrary code via (1) a URL with a long UTF-8 string, which triggers the overflow when the user highlights it, or (2) a font HTML tag with a face attribute containing a long UTF-8 string.

Cerulean Studios Trillian Pro before 3.1.5.1 allows remote attackers to obtain potentially sensitive information via long CTCP PING messages that contain UTF-8 characters, which generates a malformed response that is not truncated by a newline, which can cause portions of a server message to be sent to the attacker.

Heap-based buffer overflow in Cerulean Studios Trillian 3.x before 3.1.6.0 allows remote attackers to execute arbitrary code via a message sent through the MSN protocol, or possibly other protocols, with a crafted UTF-8 string, which triggers improper memory allocation for word wrapping when a window width is used as a buffer size, a different vulnerability than CVE-2007-2478.

Buffer overflow in the AOL Instant Messenger (AIM) protocol handler in AIM.DLL in Cerulean Studios Trillian allows remote attackers to execute arbitrary code via a malformed aim: URI, as demonstrated by a long URI beginning with the aim:///#1111111/ substring.

The AOL Instant Messenger (AIM) protocol handler in Cerulean Studios Trillian allows remote attackers to create files with arbitrary contents via certain aim: URIs, as demonstrated by a URI that begins with the "aim: &c:\" substring and contains a full pathname in the ini field. NOTE: this can be leveraged for code execution by writing to a Startup folder.

Buffer overflow in the Display Names message feature in Cerulean Studios Trillian Basic and Pro 3.1.9.0 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long nickname in an MSN protocol message.

Stack-based buffer overflow in Cerulean Studios Trillian before 3.1.10.0 allows remote attackers to execute arbitrary code via unspecified attributes in the X-MMS-IM-FORMAT header in an MSN message.

Stack-based buffer overflow in the image tooltip implementation in Trillian before 3.1.12.0 allows remote attackers to execute arbitrary code via a long image filename, related to "AIM IMG Tag Parsing."

Double free vulnerability in the XML parser in Trillian before 3.1.12.0 allows remote attackers to execute arbitrary code via a crafted XML expression, related to the "IMG SRC ID."

Heap-based buffer overflow in the XML parser in the AIM plugin in Trillian before 3.1.12.0 allows remote attackers to execute arbitrary code via a malformed XML tag.

Trillian 1.0 Pro and 0.74 Freeware allows remote attackers to cause a denial of service (crash) via a TypingUser message in which the "TypingUser" string has been modified.

Buffer overflow in the MSN module in Trillian 0.74i allows remote MSN servers to execute arbitrary code via a long string that ends in a newline character.

Integer overflow in Trillian 0.74 and earlier, and Trillian Pro 2.01 and earlier, 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.

Stack-based buffer overflow in Trillian 0.71 through 0.74f and Trillian Pro 1.0 through 2.01 allows remote attackers to execute arbitrary code via a Yahoo Messenger packet with a long key name.

Buffer overflow in Trillian 3.0 and Pro 3.0 allows remote attackers to execute arbitrary code via a crafted PNG image file.

Multiple buffer overflows in the (1) AIM, (2) MSN, (3) RSS, and other plug-ins for Trillian 2.0 allow remote web servers to cause a denial of service (application crash) via a long string in an HTTP 1.1 response header.

Multiple buffer overflows in the Yahoo plug-in for Trillian 2.0, 3.0, and 3.1 allow remote web servers to cause a denial of service (application crash) via a long string in an HTTP 1.1 response header.

Trillian Pro 3.1 build 121, when checking Yahoo e-mail, stores the password in plaintext in a world readable file and does not delete the file after login, which allows local users to obtain sensitive information.

Cerulean Studios Trillian 3.0 allows remote attackers to cause a denial of service (crash) via a reverse direct connection from a different client, as demonstrated using LICQ.
