high Nessus Plugin ID 18929

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

3APA3A reports :

If programmer fails to check socket number before using select() or fd_set macros, it's possible to overwrite memory behind fd_set structure. Very few select() based application actually check FD_SETSIZE value. [...]

Depending on vulnerable application it's possible to overwrite portions of memory. Impact is close to off-by-one overflows, code execution doesn't seems exploitable.
