FreeBSD : fd_set -- bitmap index overflow in multiple applications (4c005a5e-2541-4d95-80a0-00c76919aa66)

High Nessus Plugin ID 18929


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


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.


Update the affected packages.
