CVE-2018-16948 (opens in a new tab)How to fix?
Upgrade Debian:unstable openafs to version 1.8.2-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openafs package and not the openafs package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several RPC server routines did not fully initialize their output variables before returning, leaking memory contents from both the stack and the heap. Because the OpenAFS cache manager functions as an Rx server for the AFSCB service, clients are also susceptible to information leakage. For example, RXAFSCB_TellMeAboutYourself leaks kernel memory and KAM_ListEntry leaks kaserver memory.
