Synopsis
=======
A buffer overflow and a format string vulnerability in aria2 allow
remote attackers to execute arbitrary code.

Background
=========
aria2 is a download utility with resuming and segmented downloading
with HTTP/HTTPS/FTP/BitTorrent support.

Affected packages
================
    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  net-misc/aria2       < 1.6.3                             >= 1.6.3

Description
==========
Tatsuhiro Tsujikawa reported a buffer overflow in
DHTRoutingTableDeserializer.cc (CVE-2009-3575) and a format string
vulnerability in the AbstractCommand::onAbort() function in
src/AbstractCommand.cc (CVE-2009-3617).

Impact
=====
A remote, unauthenticated attacker could possibly execute arbitrary
code with the privileges of the user running the application or cause a
Denial of Service (application crash).

Workaround
=========
Do not use DHT (CVE-2009-3575) and disable logging (CVE-2009-3617).

Resolution
=========
All aria2 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/aria2-1.6.3"
