Title:	Western Digital My Cloud Multiple Products 5.0 < 5.21.104 Samba Vulnerability (WDC-22006)
Summary:	Multiple Western Digital My Cloud products are prone to a; vulnerability in Samba.
Description:	Summary: Multiple Western Digital My Cloud products are prone to a vulnerability in Samba. Vulnerability Insight: Samba is vulnerable to an out-of-bounds heap read write vulnerability that allows remote attackers to execute arbitrary code as root on affected Samba installations that use the VFS module vfs_fruit. The specific flaw exists within the parsing of EA metadata when opening files in smbd. Access as a user that has write access to a file's extended attributes is required to exploit this vulnerability. Note that this could be a guest or unauthenticated user if such users are allowed write access to file extended attributes. The problem in vfs_fruit exists in the default configuration of the fruit VFS module using fruit:metadata=netatalk or fruit:resource=file. If both options are set to different settings than the default values, the system is not affected by the security issue. Affected Software/OS: Western Digital My Cloud PR2100, My Cloud PR4100, My Cloud EX4100, My Cloud EX2 Ultra, My Cloud Mirror Gen 2, My Cloud DL2100, My Cloud DL4100, My Cloud EX2100, My Cloud and WD Cloud with firmware versions prior to 5.21.104. Solution: Update to firmware version 5.21.104 or later. CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
