Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a stack based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12041). JT2Go and Teamcenter Visualization Is vulnerable to an out-of-bounds write. Zero Day Initiative To this vulnerability ZDI-CAN-12041 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. 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 parsing of PAR files",
