Summary

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.
