Debian DLA-1982-1 : openafs security update

high Nessus Plugin ID 130523

Synopsis

The remote Debian host is missing a security update.

Description

Several security vulnerabilities were discovered in OpenAFS, a distributed file system.

CVE-2019-18601

OpenAFS is prone to denial of service from unserialized data access because remote attackers can make a series of VOTE_Debug RPC calls to crash a database server within the SVOTE_Debug RPC handler.

CVE-2019-18602

OpenAFS is prone to an information disclosure vulnerability because uninitialized scalars are sent over the network to a peer.

CVE-2019-18603

OpenAFS is prone to information leakage upon certain error conditions because uninitialized RPC output variables are sent over the network to a peer.

For Debian 8 'Jessie', these problems have been fixed in version 1.6.9-2+deb8u9.

We recommend that you upgrade your openafs packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
