CVE-2018-12088 (opens in a new tab)How to fix?
There is no fixed version for Debian:8 s3ql.
NVD Description
Note: Versions mentioned in the description apply only to the upstream s3ql package and not the s3ql package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is related to the checksum_basic_mapping function.
