4) Description of Vulnerability

Secunia Research has discovered a vulnerability in the IMail Client, which potentially can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the IMail Client when processing emails containing multipart MIME data. This can be exploited to cause a data segment-based buffer overflow via an overly long "boundary" parameter (more than 212 bytes).
