aria2: Multiple vulnerabilities — GLSA 201001-06

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

Affected Packages

net-misc/aria2 on all architectures
Affected versions < 1.6.3
Unaffected versions >= 1.6.3

Background

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

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"
