Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The OpenAFS development team reports :

When constructing an Rx acknowledgment (ACK) packet, Andrew-derived Rx implementations do not initialize three octets of data that are padding in the C language structure and were inadvertently included in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0 through 1.7.32 include a variable-length padding at the end of the ACK packet, in an attempt to detect the path MTU, but only four octets of the additional padding are initialized (CVE-2015-7763).

Solution

Update the affected package.
