3) Vendor's Description of Software
"aria2 is a lightweight multi-protocol & multi-source, cross platform
download utility operated in command-line.".
Product Link:
http://aria2.sourceforge.net/
======================================================================
4) Description of Vulnerability
Secunia Research has discovered a vulnerability in aria2, which can be
exploited by malicious people to compromise a user's system.
The vulnerability is caused due to the application not properly
sanitising 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 Common Vulnerabilities and Exposures (CVE) project has assigned
CVE-2010-1512 for the vulnerability.
