CWE-20
CVSS Score:
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:X/RL:X/RC:X

attacker to cause the video service to crash, resulting in a DoS condition
on an affected device.
Cisco has released software updates that address these vulnerabilities.
There are no workarounds that address these vulnerabilities.
