An exploitable buffer overflow vulnerability exists in the tag parsing functionality of LibOFX 0.9.11. A specially crafted OFX file can cause a write out of bounds resulting in a buffer overflow on the stack. An attacker can construct a malicious OFX file to trigger this vulnerability.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
