bogofilter Unicode database buffer overflow
| bogofilter-unicode-bo (24118) |  High Risk |
Description:
bogofilter is vulnerable to a heap-based buffer overflow when configured to use a Unicode database. By creating a malicious email containing invalid input sequences, a remote attacker could overflow a buffer and cause the application to crash and possibly execute arbitrary code on the system, once bogofilter processes the malicious email.
