out-of-bounds read in Parasolid IGES Translator < 29.0.258
CVE-2025-40936 Published on November 17, 2025
A vulnerability has been identified in PS/IGES Parasolid Translator Component (All versions < V29.0.258), Simcenter Femap (All versions < V2512.0003), Solid Edge (All versions < V226.00 Update 03). The affected applications contains an out of bounds read vulnerability while parsing specially crafted IGS files. This could allow an attacker to crash the application or execute code in the context of the current process. (ZDI-CAN-26755)
Weakness Type
Out-of-bounds Read
The software reads data past the end, or before the beginning, of the intended buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.
