Name of the Vulnerable Software and Affected Versions F2fs-Tools versions 1.13

Description The issue is related to incorrect external management of file names or paths, which can be exploited to delete arbitrary files by creating a specially crafted f2fs filesystem. A specially crafted f2fs filesystem can cause information overwrite, resulting in code execution. An attacker can provide a malicious file to trigger this vulnerability.

Recommendations For version 1.13, consider restricting the use of the F2fs.Fsck functionality until a patch is available. As a temporary workaround, avoid using F2fs-Tools to handle untrusted or malicious filesystems.
