  script_set_attribute(attribute:"description", value:
"A vulnerability in the H.323 subsystem of Cisco IOS and IOS XE Software 
could allow an unauthenticated, remote attacker to create a denial of service 
(DoS) condition on an affected device. 
The vulnerability is due to a failure to properly validate certain fields in 
an H.323 protocol suite message. When processing the malicious message, 
the affected device may attempt to access an invalid memory region, 
resulting in a crash. An attacker who can submit an H.323 packet designed 
to trigger the vulnerability could cause the affected device to crash and restart.
