Name of the Vulnerable Software and Affected Versions Cisco IOS versions 12.4 through 15.2

Description The issue is related to a memory leak in the Zone-Based Firewall component of Cisco IOS, which can be exploited by sending crafted IP packets, leading to a denial of service due to memory consumption or device reload. This is caused by errors in the implementation of the Cisco IOS Zone-Based Firewall. The estimated number of potentially affected devices is not specified.

Recommendations For Cisco IOS versions 12.4 through 15.2, update to a version that includes the fix for this issue, as software updates have been released by Cisco to address these vulnerabilities.
