high Nessus Plugin ID 89766

Synopsis

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

Description

Mozilla Foundation reports :

Security researcher Hanno Bock reported that calculations with mp_div and mp_exptmod in Network Security Services (NSS) can produce wrong results in some circumstances. These functions are used within NSS for a variety of cryptographic division functions, leading to potential cryptographic weaknesses.

Mozilla developer Eric Rescorla reported that a failed allocation during DHE and ECDHE handshakes would lead to a use-after-free vulnerability.

Solution

Update the affected packages.
