Description

An unauthenticated stack-based buffer overflow vulnerability exists in vlsvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient length validation when processing remote login data. A remote attacker may exploit this vulnerability by sending crafted login data with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution.
