Title:	Samba RCE Vulnerability (CVE-2021-44142)
Summary:	Samba is prone to a remote code execution (RCE) vulnerability.
Description:	Summary: Samba is prone to a remote code execution (RCE) vulnerability. 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: Samba versions prior to 4.13.17, version 4.14.x through 4.14.11 and 4.15.x through 4.15.4. Solution: Update to version 4.13.17, 4.14.12, 4.15.5 or later. CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
