Vulnerability from variot
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. Samba administrators are advised to upgrade to these releases or apply the patch as soon as possible.
================== 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.

samba vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.10
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in Samba.
Software Description: - samba: SMB/CIFS file, print, and login server for Unix
Details:
Orange Tsai discovered that the Samba vfs_fruit module incorrectly handled certain memory operations. (CVE-2021-44142)
Michael Hanselmann discovered that Samba incorrectly created directories. In certain configurations, a remote attacker could possibly create a directory on the server outside of the shared directory. (CVE-2021-43566)
Kees van Vloten discovered that Samba incorrectly handled certain aliased SPN checks. (CVE-2022-0336)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.10: samba 2:4.13.17~dfsg-0ubuntu0.21.10.1
Ubuntu 20.04 LTS: samba 2:4.13.17~dfsg-0ubuntu0.21.04.1
This update uses a new upstream release, which includes additional bug fixes. In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

"data": "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. \n\nThe specific flaw exists within the parsing of EA metadata when\nopening files in smbd. \n\nThe problem in vfs_fruit exists in the default configuration of the\nfruit VFS module using fruit:metadata=netatalk or fruit:resource=file. \nIf both options are set to different settings than the default values,\nthe system is not affected by the security issue. \n\n==================\nPatch Availability\n==================\n\nPatches addressing both these issues have been posted to:\n\n https://www.samba.org/samba/security/\n\nAdditionally, Samba 4.13.17, 4.14.12 and 4.15.5 have been issued as\nsecurity releases to correct the defect. Samba administrators are\nadvised to upgrade to these releases or apply the patch as soon\nas possible. \n\n==================\nCVSSv3 calculation\n==================\n\nCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C\n\nBase score 9.9. \n\n==========\nWorkaround\n==========\n\nAs a workaround remove the \"fruit\" VFS module from the list of\nconfigured VFS objects in any \"vfs objects\" line in the Samba\nconfiguration smb.conf. \n\nNote that changing the VFS module settings fruit:metadata or\nfruit:resource to use the unaffected setting causes all stored\ninformation to be inaccessible and will make it appear to macOS\nclients as if the information is lost. \n\n\n=======\nCredits\n=======\n\nOriginally reported by Orange Tsai from DEVCORE. \n\nPatches provided by Ralph B\u00f6hme of the Samba team. \n\n==========================================================\n== Our Code, Our Bugs, Our Responsibility. \n== The Samba Team\n==========================================================\n.

(CVE-2021-44142)\n\nMichael Hanselmann discovered that Samba incorrectly created directories. \nIn certain configurations, a remote attacker could possibly create a\ndirectory on the server outside of the shared directory. (CVE-2021-43566)\n\nKees van Vloten discovered that Samba incorrectly handled certain aliased\nSPN checks. (CVE-2022-0336)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 21.10:\n samba 2:4.13.17~dfsg-0ubuntu0.21.10.1\n\nUbuntu 20.04 LTS:\n samba 2:4.13.17~dfsg-0ubuntu0.21.04.1\n\nThis update uses a new upstream release, which includes additional bug\nfixes. In general, a standard system update will make all the necessary\nchanges. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n==================================================================== \nRed Hat Security Advisory\n\nSynopsis: Critical: samba security and bug fix update\nAdvisory ID: RHSA-2022:0328-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2022:0328\nIssue date: 2022-01-31\nCVE Names: CVE-2021-44142\n====================================================================\n1.
