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) Input validation error (CVE-ID: CVE-2024-24789)

The vulnerability allows a remote attacker to manipulate data.

The vulnerability exists due to insufficient validation of user-supplied input in archive/zip when handling zip archives. A remote attacker can create a zip file with content that will vary depending on the implementation reading the file.
