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"
