Summary
MicroStation applications may be affected by out-of-bounds read and stack overflow vulnerabilities when opening maliciously crafted XMT (Parasolid) files. Exploiting these vulnerabilities could lead to information disclosure or arbitrary code execution.
Details
Using an affected version of MicroStation to open a JT file containing maliciously crafted data can possibly force an out-of-bounds read or force the execution of arbitrary code. Exploitation of these vulnerabilities within the parsing of JT files could enable an attacker to read information or execute code in the context of the current process.
