This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.\n\nThe specific flaw exists within the parsing of XE files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer.
