Secunia Research has discovered a vulnerability in Internet Download Manager, which can be exploited by malicious people to compromise a user’s system. The vulnerability is caused by a boundary error when sending certain test sequences to an FTP server. This can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into downloading a file from a specially crafted FTP URI. Successful exploitation allows execution of arbitrary code. Internet Download Manager version 5.18 is affected.
