Samba 4.x < 4.10.17 / 4.11.x < 4.11.11 / 4.12.x < 4.12.4 Multiple Vulnerabilities

The version of Samba running on the remote host is 4.x prior to 4.10.17, 4.11.x prior to 4.11.11, or 4.12.x prior to 4.12.4. It is, therefore, affected by multiple vulnerabilities, including the following: - The AD DC NBT server in Samba 4.0 will enter a CPU spin and not process further requests...

CVE-2020-10745

A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this...

CVE-2020-10745

CVE-2020-10745 affects Samba (notably AD DC) and is caused by abuse of compression in replies to NetBIOS over TCP/IP name resolution and DNS packets, leading to excessive CPU usage and a denial of service. The vulnerability impacts Samba versions prior to 4.10.17, 4.11.11, and 4.12.4. Remediation...

Empty UDP packet DoS in Samba AD DC nbtd

Description The NetBIOS over TCP/IP name resolution protocol is implemented as a UDP datagram on port 137. The AD DC client and server-side processing code for NBT name resolution will enter a tight loop if a UDP packet with 0 data length is received. The client for this case is only found in the...

Parsing and packing of NBT and DNS packets

Description The NetBIOS over TCP/IP name resolution protocol is framed using the same format as DNS, and Samba's packing code for both uses DNS name compression. An attacker can choose a name which, when the name is included in the reply, causes the DNS name compression algorithm to walk a very...
