Description:
A vulnerability has been reported in Adobe Download Manager, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when handling section names in the "dm.ini" file as created by Adobe Download Manager when processing AOM files. This can be exploited to cause a stack-based buffer overflow via a specially crafted AOM or "dm.ini" file.

Successful exploitation allows execution of arbitrary code when a user e.g. visits a malicious website.

The vulnerability is reported in version 2.1 and earlier.
