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"
