Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Link following (CVE-ID: CVE-2023-4759)

The vulnerability allows a remote attacker to overwrite files on the system.

The vulnerability exists due to an insecure link following. A remote attacker can place a specially crafted symbolic link into the repository, trick the victim into cloning it and overwrite arbitrary files on the system.


2) UNIX symbolic link following (CVE-ID: CVE-2023-35887)

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

The vulnerability exists due to insecure symlink following that lead to files outside the RootedFileSystem. A remote user can identify presence of files on the system.


3) Excessive Iteration (CVE-ID: CVE-2023-4043)

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

The vulnerability exists due to built-in support for parsing numbers with large scale in Java has a number of edge cases where the input text of a number can lead to much larger processing time than one would expect. A remote attacker can trigger excessive iteration and perform a denial of service (DoS) attack.


4) 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.
