Package : openafs
Version : 1.6.9-2+deb8u9
CVE ID : CVE-2019-18601 CVE-2019-18602 CVE-2019-18603
Debian Bug : 943587
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.
