A buffer overflow was addressed with improved bounds checking. This issue is fixed in macOS Monterey 12.6.6, macOS Big Sur 11.7.7, macOS Ventura 13.4. Parsing an office document may lead to an unexpected app termination or arbitrary code execution.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
