Cisco IOS Software Border Gateway Protocol 4-Byte Autonomous System Number Vulnerabilities
vendor_cisco·2009-07-29·CVSS 7.1
CVE-2009-1168 [HIGH] CWE-399 Cisco IOS Software Border Gateway Protocol 4-Byte Autonomous System Number Vulnerabilities
Cisco IOS Software Border Gateway Protocol 4-Byte Autonomous System Number Vulnerabilities
Recent versions of Cisco IOS Software support RFC4893 ("BGP Support for
Four-octet AS Number Space") and contain two remote denial of service (DoS)
vulnerabilities when handling specific Border Gateway Protocol (BGP) updates.
These vulnerabilities affect only devices running Cisco IOS Software
with support for four-octet AS number space (here after referred to as 4-byte
AS number) and BGP routing configured.
The first vulnerability could cause an affected device to reload when
processing a BGP update that contains autonomous system (AS) path segments made
up of more than one thousand autonomous systems.
The second vulnerability could cause an affected device to reload when
the affected device pro
