The version of Siemens JT2Go installed on the remote Windows hosts is prior to 13.1.0.3. It is, therefore, affected by a code execution vulnerability. The TIFF_loader.dll library in affected applications lacks proper validation of user-supplied data when parsing TIFF files. This could result in an out of bounds write past the end of an allocated structure. An attacker could leverage this vulnerability to execute code in the context of the current process.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
