Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
An exploitable code execution vulnerability exists in the multiple devices functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause Information overwrite resulting in a code execution. An attacker can provide a malicious file to trigger this vulnerability.
