Detailsinfo

A vulnerability, which was classified as problematic, was found in Cisco RoomOS Software and TelePresence Endpoint Software (version now known). Affected is some unknown processing of the component Text Rendering Subsystem. The manipulation with an unknown input leads to a improper validation of specified type of input vulnerability. CWE is classifying the issue as CWE-1287. The product receives input that is expected to be of a certain type, but it does not validate or incorrectly validates that the input is actually of the expected type. This is going to have an impact on availability. CVE summarizes:

A vulnerability in the text rendering subsystem of Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of input received by an affected device. An attacker could exploit this vulnerability by getting the affected device to render crafted text, for example, a crafted meeting invitation. As indicated in the CVSS score, no user interaction is required, such as accepting the meeting invitation. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.
