TITLE:
Free Download Manager Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA39447

VERIFY ADVISORY:
http://secunia.com/advisories/39447/

DESCRIPTION:
Secunia Research has discovered some vulnerabilities in Free Download
Manager, which can be exploited by malicious people to compromise a
user's system.

1) A boundary error when opening folders within the "Site Explorer"
functionality can be exploited to cause a stack-based buffer
overflow.

2) A boundary error when e.g. opening websites in the "Site Explorer"
functionality can be exploited to cause a stack-based buffer
overflow.

3) A boundary error when setting the directory on FTP servers can be
exploited to cause a stack-based buffer overflow.

4) A boundary error when handling redirects can be exploited to cause
a stack-based buffer overflow.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.

5) The application does not properly sanitise the "name" attribute of
the "file" element of metalink files before using it to download
files. If a user is tricked into downloading from a specially crafted
metalink file, this can be exploited to download files to directories
outside of the intended download directory via directory traversal
attacks.

The vulnerabilities are confirmed in version 3.0 build 850. Other
versions may also be affected.

SOLUTION:
Update to version 3.0 build 852.

PROVIDED AND/OR DISCOVERED BY:
