A security flaw has been discovered in vim up to 9.1.1615. Affected by this vulnerability is the function main of the file src/xxd/xxd.c of the component xxd. The manipulation results in buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be exploited. Upgrading to version 9.1.1616 addresses this issue. The patch is identified as eeef7c77436a78cd27047b0f5fa6925d56de3cb0. It is recommended to upgrade the affected component.
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.
