CVE-2019-11878
An attacker on the same local network as the camera can craft a message with a size field larger than 0x80000000 and send it to the camera, related to an integer overflow or use of a negative number.
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
