CVE-2024-39894

OpenSSH CVE-2024-39894 affects OpenSSH 9.5–9.7 (before 9.8). A logic error in the ObscureKeystrokeTiming feature can enable timing attacks on keystroke entry (e.g., echo-off password input for su and sudo) and potentially reveal keystrokes. Mitigation per linked advisories is to upgrade to OpenSS...

Name of the Vulnerable Software and Affected Versions: OpenSSH versions 9.5 through 9.7 Description: The issue is related to a logic error in the ObscureKeystrokeTiming function, which can lead to timing attacks against echo-off password entry, such as those used for su and Sudo. This could...

Time-Based Information Disclosure Vulnerability in Flow

The PersistedUsernamePasswordProvider was prone to a information disclosure of account existance based on timing attacks as the hashing of passwords was only done in case an account was found. We changed the core so that the provider always does a password comparison in case credentials were...

ssh: Prefix truncation attack on Binary Packet Protocol (BPP)

A flaw was found in the SSH channel integrity. By manipulating sequence numbers during the handshake, an attacker can remove the initial messages on the secure channel without causing a MAC failure. For example, an attacker could disable the ping extension and thus disable the new countermeasure ...
