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 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.

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.

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.

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.

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.

Cerulean Trillian 3.1.0.120 allows remote attackers to cause a denial of service (client crash) via an AIM message containing the Mac encoded Rich Text Format (RTF) escape sequences (1) \'d1, (2) \'d2, (3) \'d3, (4) \'d4, and (5) \'d5. NOTE: the provenance of this information is unknown; the details are obtained solely from third party 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.

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.

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.
