USN-6663-1: OpenSSL update

As a security improvement, OpenSSL will now return deterministic random bytes instead of an error when detecting wrong padding in PKCS1 v1.5 RSA to prevent its use in possible Bleichenbacher timing attacks...

PT-2024-20804

Name of the Vulnerable Software and Affected Versions libjwt version 1.15.3 Description The issue arises from the use of strcmp to verify authentication, which is not a constant time operation. This makes it easier for attackers to bypass authentication via a timing side channel. Recommendations...

The container-tools module contains tools for working with containers, notably podman, buildah, skopeo, and runc. Security Fixes: runc: file...

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 ...

CVE-2023-45287

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...

CVE-2023-45287

Summary of CVE-2023-45287 (Go): Before Go 1.20, RSA-based TLS key exchanges used math/big (not constant time). RSA blinding was applied but may not fully prevent timing leaks after removal of PKCS#1 padding, potentially enabling recovery of session key bits. Go 1.20+ switched crypto/tls to a full...

Non-constant time token comparison in google-login

google-login 1.7 and earlier does not use a constant-time comparison when checking whether the provided and expected token are equal. This could potentially allow attackers to use statistical methods to obtain a valid token. google-login 1.8 uses a constant-time comparison when validating the tok...

Cross site request forgery (csrf)

Oppia is an online learning platform. When comparing a received CSRF token against the expected token, Oppia uses the string equality operator ==, which is not safe against timing attacks. By repeatedly submitting invalid tokens, an attacker can brute-force the expected CSRF token character by...

Non-constant time token comparison in tuleap-oauth

tuleap-oauth 1.1.20 and earlier does not use a constant-time comparison when checking whether two authentication tokens are equal. This could potentially allow attackers to use statistical methods to obtain a valid authentication token. tuleap-oauth 1.1.21 uses a constant-time comparison when...

Medium: python-rsa

Issue Overview: A flaw was found in python-rsa, where it is vulnerable to Bleichenbacher timing attacks. This flaw allows an attacker, via the RSA decryption API, to decrypt parts of the ciphertext encrypted with RSA. The highest threat from this vulnerability is to confidentiality. CVE-2020-2565...
