Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.

Security Fix(es):

  • samba: smbd allows client access to unix domain sockets on the file system as root (CVE-2023-3961)

  • samba: SMB clients can truncate files with read-only permissions (CVE-2023-4091)

  • samba: “rpcecho” development server allows denial of service via sleep() call on AD DC (CVE-2023-42669)
