Name of the Vulnerable Software and Affected Versions Cisco IOS versions 12.1 through 12.4 Cisco IOS versions 15.0 through 15.1

Description The issue affects the NAT for H.225.0 implementation, allowing remote attackers to cause a denial of service (device reload) via transit traffic. It is part of three denial of service vulnerabilities in the Cisco IOS Software Network Address Translation functionality, specifically in the translation of H.225.0 call signaling for H.323 packets.

Recommendations For Cisco IOS versions 12.1 through 12.4, update to a version that addresses these vulnerabilities. For Cisco IOS versions 15.0 through 15.1, update to a version that addresses these vulnerabilities. As a temporary workaround, consider restricting the translation of H.225.0 call signaling for H.323 packets until a patch is available.
