CVE-2020-6108
Estado: ModificadaAlta (7.8)—
An exploitable code execution vulnerability exists in the fsck_chk_orphan_node functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause a heap buffer overflow resulting in a code execution. An attacker can provide a malicious file to trigger this vulnerability.
