high Nessus Plugin ID 130244

Language:

Synopsis

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

Description

Due do a missing check in the code of m_pulldown(9) data returned may not be contiguous as requested by the caller. Impact : Extra checks in the IPv6 code catch the error condition and trigger a kernel panic leading to a remote DoS (denial-of-service) attack with certain Ethernet interfaces. At this point it is unknown if any other than the IPv6 code paths can trigger a similar condition.

Solution

Update the affected packages.
