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.
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.
