What it is

An unauthenticated

stack-based buffer overflow vulnerability exists in ssvr in GeoVision

GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by

insufficient bounds checking when parsing RTSP Digest authentication fields. A

remote attacker may exploit this vulnerability by sending a crafted RTSP

request containing overly long authentication data, resulting in memory

corruption, denial of service, or potentially arbitrary code execution.
