Three vulnerabilities plague Samba, including one critical and one high severity vulnerability. Specifically, remote attackers can exploit them to execute arbitrary code, scaling root privileges, and take control of servers running the vulnerable software.
Samba requires an immediate update. Three vulnerabilities plague the open source implementation of the SMB protocol. One vulnerability is critical and another is high severity. The CVE-2021-44142 flaw (rated 9.9 on the CVSS scale) in the Samba project is extremely concerning.
Samba is the project that was created to provide file and printer sharing services and is a crucial element in ensuring interoperability between Unix, Linux, macOS and Windows systems. Server Message Block (SMB) is a networking protocol used for sharing files, ports and printers across different platforms. Speaking of Linux, the flaw afflicts Red Hat, SUSE Linux and Ubuntu distributions.
Samba has released the software update to patch multiple exploit-prone vulnerabilities.
Samba has released the software update to patch multiple exploit-prone vulnerabilities. System administrators should immediately update the protocol to versions 4.13.17, 4.14.12 or 4.15.5 or fix the flaw using the security patches already distributed.
