Remove netatalk 3 Patch#
Samba administrators should upgrade to these releases or apply the patch as soon as possible to mitigate the defect and thwart any potential attacks exploiting the vulnerability. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding any service principals names (SPN) that matches an existing service.
The patch for this vulnerability was included in a security updatethat also patches some other issues: If both options are set to different settings than the default values, the system is not affected by the security issue. The problem in vfs_fruit exists in the default configuration of the fruit VFS module using fruit:metadata=netatalkor fruit:resource=file. In this case as root, which is the user name or account that by default has access to all commands and fileson a Linux or other Unix-like operating system.

This can allow an attacker to write code to a part of the memory where it will be executed with permissions that the program and user should not have. If a flaw in a program allows it to read or write outside of the bounds set for the program, it is possible to manipulate other parts of the memory which are allocated to more critical functions. The heap is the name for the part of the system’s memory that is allocated for the use of programs. The vulnerability is described as an out-of-bounds heap read/write vulnerability. The vulnerability in Samba that received a CVSS scoreof 9.9 out of 10 has been assigned CVE-2021-44142. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database.
A UNIX, Linux or BSD system running Netatalk is capable of serving many Macintosh clients simultaneously as an AppleShare file server (AFP). Netatalk is a freely-available Open Source AFP fileserver. The vfs_fruit module provides enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver.

Samba is a free software re-implementation of the SMBnetworking protocol that provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain. Samba developers have patched a vulnerabilitythat allows remote attackers to execute arbitrary code as root on affected Samba installations that use the VFS module vfs_fruit.
