Upgrade Debian:12 openafs to version 1.6.17-1 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:12 relevant fixed versions and status.
The client in OpenAFS before 1.6.17 does not properly initialize the (1) AFSStoreStatus, (2) AFSStoreVolumeStatus, (3) VldbListByAttributes, and (4) ListAddrByAttributes structures, which might allow remote attackers to obtain sensitive memory information by leveraging access to RPC call traffic.
