"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."
