Some vulnerabilities have been reported in Bogofilter, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) A boundary error exists in bogofilter and bogolexer when performing character set conversion on invalid input sequences. This can be exploited to cause a heap-based buffer overflow and can cause the application to crash via an email containing specially crafted binary attachments.
Successful exploitation requires that bogofilter is used with an unicode database.
The vulnerability has been reported in the following versions:
* bogofilter (stable) 0.96.2, 0.95.2, 0.94.14, 0.94.12
* bogofilter (current) 0.93.5 through 0.96.2
2) A boundary error exists in bogofilter and bogolexer when processing input containing overly long words. This can be exploited to cause a heap-based buffer overflow and crashes the application if the input contains words whose length exceed 16,384 bytes.
The vulnerability has been reported in version 0.96.2.
