This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Wecon LeviStudioU. 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 within the FontLib.dll module. Strings read from input are not properly checked for null-terminating characters before using them later in memory read/write calls. An attacker can leverage this vulnerability to execute code in the context of the current process.
