JT File Parser OOB Read in JT Open/JT Utilities/Parasolid (< V11.4/ V13.4/ V35.1)
CVE-2023-30795 Published on August 8, 2023
A vulnerability has been identified in JT Open (All versions < V11.4), JT Utilities (All versions < V13.4), Parasolid V34.0 (All versions < V34.0.253), Parasolid V34.1 (All versions < V34.1.243), Parasolid V35.0 (All versions < V35.0.177), Parasolid V35.1 (All versions < V35.1.073). The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted JT files. This could allow an attacker to execute code in the context of the current process.
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.
