Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Inadequate encryption strength (CVE-ID: CVE-2023-48795)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.

The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.


2) Improper Authorization (CVE-ID: CVE-2023-3961)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to improper input validation when handling client pipe names. A remote attacker can provide a specially crafted pipe name containing directory traversal characters and force Samba to connect to Unix domain sockets outside of the private directory meant to restrict the services a client could connect to.The connection to Unix domain sockets is performed as root, which means that if client sends a pipe name that resolved to an external service using an existing Unix domain socket, the client is able to connect to it without any filesystem restrictions.


3) Information disclosure (CVE-ID: CVE-2023-4154)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a design error in Samba's implementation of the DirSync control, which can allow replication of critical domain passwords and secrets by Active Directory accounts authorized to do some replication, but not to replicate sensitive attributes. A remote user can obtain sensitive information from the AD DC and compromise the Active Directory.


4) Resource management error (CVE-ID: CVE-2023-42670)

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application when Samba RPC server is under load, which can lead to incorrect start of servers not built for the AD DC. A remote user can cause a high load to Samba RPC server and perform a denial of service (DoS) attack.
