FreeBSD : FreeBSD -- Kernel memory disclosure in freebsd32_ioctl (6b856e00-b30a-11e9-a87f-a4badb2f4699)

Medium Nessus Plugin ID 127546

Synopsis

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

Description

Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes. Impact : A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory.

Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.

Solution

Update the affected packages.
