Effective 2019 Sep 15, Cisco will no longer publish non-Cisco product alerts. Cisco will continue to publish Security Advisories to address third-party software vulnerabilities per the Cisco Security Vulnerability Policy.
IntelliShield has updated this alert to include additional affected releases related to the Cisco IOS-XE Software fragmented packet resource consumption vulnerability.
To exploit the vulnerability, an attacker must send a continuous series of network packets to a targeted device. Devices that are protected by network filtering or have access restricted from untrusted networks may be at less risk of exploitation.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
Cisco has released bug ID CSCuo37957 for registered users, which contains additional details and an up-to-date list of affected product versions.
Version 1, July 29, 2015, 4:04 PM: Cisco IOS-XE Software contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition. Updates are available.
