CVE-2025-27193 is a critical heap-based buffer overflow vulnerability affecting Bridge versions 14.1.5, 15.0.2, and earlier. The flaw occurs when parsing maliciously crafted files, leading to memory corruption. Attackers exploit this by tricking users into opening a specially designed file, triggering an overflow in the heap memory region. This allows arbitrary code execution under the victim’s privileges due to insufficient bounds checking during file processing.
The vulnerability leverages improper memory handling in Bridge’s file-parsing component. When processing oversized or malformed data, the application fails to validate input sizes, overwriting adjacent heap structures. Successful exploitation could enable remote code execution (RCE), compromising system integrity.
