| Package | Affected versions | Patched versions |
|---|---|---|
| exim | ≥ 4.00, < 4.94.2 | 4.94.2 |
Exim 4 before 4.94.2 allows Heap-based Buffer Overflow because it mishandles "-F '.('" on the command line, and thus may allow privilege escalation from any user to root. This occurs because of the interpretation of negative sizes in strncpy.
