2. Problem description

Julius Plenz figured out that bogofilter's/bogolexer's base64 could
overwrite heap memory in the character set conversion in certain
pathological cases of invalid base64 code that decodes to incomplete
multibyte characters.

3. Impact

Vulnerable bogofilter/bogolexer applications can corrupt their heap and crash.

4. Solution

Upgrade your bogofilter to version 1.2.3 (or a newer release).

bogofilter is available from SourceForge:
