Samba Service | Breaking Cybersecurity News | The Hacker News

Samba maintainers have just released new versions of their networking software to patch two critical vulnerabilities that could allow unprivileged remote attackers to launch DoS attacks against servers and change any other users' passwords, including admin's. Samba is open-source software (re-implementation of SMB networking protocol) that runs on the majority of operating systems available today, including Windows, Linux, UNIX, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to share network shared folders, files, and printers with Windows operating system. The denial of service vulnerability, assigned CVE-2018-1050 , affects all versions of Samba from 4.0.0 onwards and could be exploited "when the RPC spoolss service is configured to be run as an external daemon." "Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash. ...

Remember SambaCry ? Two weeks ago we reported about a 7-year-old critical remote code execution vulnerability in Samba networking software (re-implementation of SMB networking protocol) that allows a remote hacker to take full control of a vulnerable Linux and Unix machines. To know more about the SambaCry vulnerability (CVE-2017-7494) and how it works, you can read our previous article . At that time, nearly 485,000 Samba-enabled computers were found to be exposed on the Internet, and researchers predicted that the SambaCry-based attacks also have potential to spread just like WannaCry ransomware widely. The prediction came out to be quite accurate, as honeypots set up by the team of researchers from Kaspersky Lab have captured a malware campaign that is exploiting SambaCry vulnerability to infect Linux computers with cryptocurrency mining software. Another security researcher, Omri Ben Bassat‏, independently discovered  the same campaign and named it "EternalMiner...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

A 7-year-old critical remote code execution vulnerability has been discovered in Samba networking software that could allow a remote attacker to take control of an affected Linux and Unix machines. Samba is open-source software (re-implementation of SMB networking protocol) that runs on the majority of operating systems available today, including Windows, Linux, UNIX, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to share network shared folders, files, and printers with Windows operating system. The newly discovered remote code execution vulnerability ( CVE-2017-7494 ) affects all versions newer than Samba 3.5.0 that was released on March 1, 2010. "All versions of Samba from 3.5.0 onwards are vulnerable to a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it," Samba wrote in an advisory published Wed...

Security researchers have discovered a nasty security vulnerability that is said to affect almost every version of Windows and Samba and will be patched on April 12, 2016, the Samba development team announced Tuesday. So, Save the Date if you are a Windows or Samba file server administrator. Samba is a free, open source implementation of the SMB/CIFS network file sharing protocol that runs on the majority of operating systems available today, including Windows, UNIX, Linux, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to communicate with the same networking protocol as the Windows products, thus enabling users to access network shared folders and files from Windows OS. Dubbed Badlock , the vulnerability has been discovered by Stefan Metzmacher, a developer of Samba Core Team. Details about the Badlock vulnerability will be disclosed on April 12, when the developers of Microsoft and Samba release security p...

A critical vulnerability has been fixed in Samba — Open Source standard Windows interoperability suite of programs for Linux and Unix, that could have allowed hackers to remotely execute an arbitrary code in the Samba daemon ( smbd ). Samba is an open source implementation of the SMB/CIFS network file sharing protocol that works on the majority of operating systems available today, which allows a non-Windows server to communicate with the same networking protocol as the Windows products. Samba is supported by many operating systems including Windows 95/98/NT, OS/2, and Linux. smbd is the server daemon of Samba which provides file sharing and printing services to clients using the SMB/CIFS protocol. Samba is also sometimes installed as a component of *BSD and OS X systems. The vulnerability, designated as CVE-2015-0240 , actually resides in this smbd file server daemon. The bug can be exploited by hackers to potentially execute code remotely with root privileges, the ...
