ALSA-2021:5082 — Important: samba security update

Affected: AlmaLinux:8: libsmbclient-devel, AlmaLinux:8: libwbclient-devel, AlmaLinux:8: samba-devel, AlmaLinux:8: samba-vfs-iouring

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: Active Directory (AD) domain user could become root on domain members (CVE-2020-25717)

* samba: SMB1 client connections can be downgraded to plaintext authentication (CVE-2016-2124)

* samba: Subsequent DCE/RPC fragment injection vulnerability (CVE-2021-23192)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

OESA-2021-1461 — samba security update

Affected: openEuler:20.03-LTS-SP1: samba, openEuler:20.03-LTS-SP2: samba

Samba is a suite of programs for Linux and Unix to interoperate with Windows. Security Fix(es): A flaw was discovered in the way samba implements SMB1 authentication. Even if Kerberos authentication is required, an attacker can use this flaw to retrieve the clear text password sent over the wire.(CVE-2016-2124) Several flaws were found in the way that samba AD DC implements storage data access and consistency checking. Attackers can use this flaw to cause damage to the entire domain.(CVE-2020-25722) A use-after-free issue was found in the Samba AD DC RPC server, which may allow handles to point to different user states, leading to more privileged access.(CVE-2021-3738) A flaw was found in the way that samba as an AD domain controller can support RODC. This will allow RODC to print administrator credentials.(CVE-2020-25718) A flaw was discovered in the way that Samba, as an AD domain controller, implements Kerberos name-based authentication. If Samba AD DC does not strictly require Kerberos PAC and always uses the SID found in it, it may not be able to distinguish the user represented by the credential.(CVE-2020-25719) The AD Kerberos acceptance service in Samba cannot perform authorization by accessing the user's unique and long-term stable identifier.(CVE-2020-25721)
