| Title | bftpd Project bftpd FTP Server 6.2 Heap-based Buffer Overflow |
|---|
| Description | A heap buffer overflow vulnerability exists in bftpd ≤ 6.2 within the `expand_groups()` function (options.c). The function appends a comma to a buffer allocated via `strdup()`, causing a 2-byte heap overflow. The issue can be triggered during processing of user commands when group definitions are parsed from a crafted configuration file, leading to process crash and potential code execution. |
