Description |
A vulnerability in the IPv6 subsystem of Cisco IOS XR Software Release
5.3.4 for the Cisco Aggregation Services Router (ASR) 9000 Series could
allow an unauthenticated, remote attacker to trigger a reload of one or
more Trident-based line cards, resulting in a denial of service (DoS)
condition. The vulnerability is due to incorrect handling of IPv6
packets with a fragment header extension. An attacker could exploit
this vulnerability by sending IPv6 packets designed to trigger the
issue either to or through the Trident-based line card. A successful
exploit could allow the attacker to trigger a reload of Trident-based
line cards, resulting in a DoS during the period of time the line card
takes to restart. This vulnerability affects Cisco Aggregation Services
Router (ASR) 9000 Series when the following conditions are met: The
router is running Cisco IOS XR Software Release 5.3.4, and the router
has installed Trident-based line cards that have IPv6 configured. A
software maintenance upgrade (SMU) has been made available that
addresses this vulnerability. The fix has also been incorporated into
service pack 7 for Cisco IOS XR Software Release 5.3.4. Cisco Bug IDs:
CSCvg46800.
