Vulnerability Insight:
Samba is an open-source implementation
of the Server Message Block (SMB) or Common Internet File System (CIFS)
protocol, which allows PC-compatible machines to share files, printers, and
other information.
A man-in-the-middle vulnerability was found in the way 'connection signing'
was implemented by Samba. A remote attacker could use this flaw to
downgrade an existing Samba client connection and force the use of plain
text. (CVE-2015-5296)
A missing access control flaw was found in Samba. A remote, authenticated
attacker could use this flaw to view the current snapshot on a Samba share,
despite not having DIRECTORY_LIST access rights. (CVE-2015-5299)
An access flaw was found in the way Samba verified symbolic links when
creating new files on a Samba share. A remote attacker could exploit this
flaw to gain access to files outside of Samba's share path. (CVE-2015-5252)
Red Hat would like to thank the Samba project for reporting these issues.
