An exploitable buffer overflow vulnerability exists in the tag parsing functionality of Ledger-CLI 3.1.1. A specially crafted journal file can cause an integer underflow resulting in code execution. An attacker can construct a malicious journal 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.
