[MEDIUM] Vulnerability Spotlight: Code execution, information disclosure vulnerabilities in F2FS toolset
## Vulnerability Spotlight: Code execution, information disclosure vulnerabilities in F2FS toolset
Vulnerabilities discovered by a Cisco Talos researcher. Blog by Jon Munshaw.
Cisco Talos recently discovered multiple code execution and information disclosure vulnerabilities in various functions of the F2FS toolset. F2FS is a filesystem toolset commonly found in embedded devices that creates, verifies and/or fixes Flash-Friendly File System files. An attacker could provide a malicious file to the target to trigger these vulnerabilities, causing a variety of negative conditions for the target.
In accordance with Cisco’s coordinated disclosure policy , we are disclosing these vulnerabilities without an update from F2FS after the organization failed to meet the 90-day deadline.
