Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Improper Authentication (CVE-ID: CVE-2023-51767)

The vulnerability allows a local user to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests. A local user can bypass authentication process and gain unauthorized access to the application by conducting a row hammer attack against the mm_answer_authpassword integer value to flip a single bit.


2) OS Command Injection (CVE-ID: CVE-2023-51385)

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation when processing user names, if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. A remote attacker can execute arbitrary OS commands via an untrusted Git repository.


3) Inadequate Encryption Strength (CVE-ID: CVE-2023-51384)

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

The vulnerability exists due to an error in the ssh-agent, which causes certain destination constraints to be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys.


4) Man-in-the-Middle (MitM) attack (CVE-ID: CVE-2025-26465)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect processing of user-supplied data in ssh(1). A remote attacker can perform server impersonation when VerifyHostKeyDNS enabled.


5) Untrusted search path (CVE-ID: CVE-2023-38408)

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

The vulnerability exists due to usage of an insecure search path within the PKCS#11 feature in ssh-agent. A remote attacker can trick the victim into connecting to a malicious SSH server and execute arbitrary code on the system, if an agent is forwarded to an attacker-controlled system.

Note, this vulnerability exists due to incomplete fix for #VU2015 (CVE-2016-10009).


6) Improper input validation (CVE-ID: CVE-2016-10009)

The vulnerability allows a remote attacker to execute arbitrary code on vulnerable ssh client.

The vulnerability exists due to incorrect handling of data passed to PKCS#11 module within ssh-agent. A remote attacker with control over sshd service can execute arbitrary code on vulnerable client.

Successful exploitation of this vulnerability may allow a remote attacker to execute arbitrary code on vulnerable client system but requires that client is connected to malicious SSH server.
