Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Matthias Andree reports :

Bogofilter's/bogolexer's input handling in version 0.96.2 was not
keeping track of its output buffers properly and could overrun a heap
buffer if the input contained words whose length exceeded 16,384
bytes, the size of flex's input buffer. A 'word' here refers to a
contiguous run of input octets that was not '_' and did not match at
least one of ispunct(), iscntrl() or isspace().
