Description

This security bulletin contains information about 2 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) Race condition (CVE-ID: CVE-2024-6409)

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

The vulnerability exists due to a race condition in portable version of sshd when handling signals. If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. A remote non-authenticated attacker can send a series of requests in order to trigger a race condition and execute arbitrary code on the system.
