TITLE

Samba vfs_fruit module insecurely handles extended file attributes

Trust: 0.8

sources: CERT/CC: VU#119678

DESCRIPTION

The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. Authentication is not required to exploit this vulnerability.The specific flaw exists within the handling of AppleDouble entries. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. The specific flaw exists within the parsing of EA metadata when opening files in smbd. 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. ================== Patch Availability ================== Patches addressing both these issues have been posted to: https://www.samba.org/samba/security/ Additionally, Samba 4.13.17, 4.14.12 and 4.15.5 have been issued as security releases to correct the defect. ================== CVSSv3 calculation ================== CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C Base score 9.9. ========== Workaround ========== As a workaround remove the "fruit" VFS module from the list of configured VFS objects in any "vfs objects" line in the Samba configuration smb.conf. Note that changing the VFS module settings fruit:metadata or fruit:resource to use the unaffected setting causes all stored information to be inaccessible and will make it appear to macOS clients as if the information is lost. ======= Credits ======= Originally reported by Orange Tsai from DEVCORE.
