Tielei Wang has discovered a vulnerability in IBM Lotus Symphony, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an integer overflow error when processing embedded image objects. This can be exploited to cause a heap-based buffer overflow via a specially crafted e.g. JPEG object within a DOC file.
Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a malicious file.
The vulnerability is confirmed in version 3.0.0 FP3 revision 20110707.1500. Other versions may also be affected.
Solution: Update to version 3.0.1.
Provided and/or discovered by: Tielei Wang via Secunia.
