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 handling of XML files. When parsing the ShortMessage SMtext element, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
