Alpine: samba: security update to 4.13.17-r0
high Tenable Cloud Security Plugin ID 407069
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility
with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to
4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via
specially crafted extended file attributes. A remote attacker with write access to extended file
attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)
- A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to
retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
(CVE-2016-2124)
- A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use
this flaw to cause possible privilege escalation. (CVE-2020-25717)
- A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC
(read-only domain controller). This would allow an RODC to print administrator tickets. (CVE-2020-25718)
- A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-
based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did
not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total
domain compromise. (CVE-2020-25719)
