Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of WECON LeviStudio. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists in the handling of LeviStudio Project files. When parsing the Driver field, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
