Cisco Cisco IOS Software Release 15.0(1)XA

CSCta19962

The H.323 implementation in Cisco IOS Software contains two vulnerabilities that may be exploited 
remotely to cause a denial of service (DoS) condition on a device that is running a vulnerable version 
of Cisco IOS Software.

Cisco has released free software updates that address these vulnerabilities. There are no 
workarounds to mitigate these vulnerabilities other than disabling H.323 on the vulnerable device if 
H.323 is not required.
