TITLE:
Orbit Downloader Long URL Parsing Buffer Overflow

SECUNIA ADVISORY ID:
SA33843

VERIFY ADVISORY:
http://secunia.com/advisories/33843/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Orbit Downloader,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error when generating
the "Connecting" log message for HTTP downloads. This can be
exploited to cause a stack-based buffer overflow by e.g. tricking a
user into downloading from a malicious HTTP server or opening a
specially crafted HTTP URL containing an overly long hostname.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 2.8.2 and 2.8.3. Other
versions may also be affected.

SOLUTION:
Update to version 2.8.5.
