An information disclosure vulnerability exists on ARM implementations that use speculative execution in control flow via a side-channel analysis, aka "straight-line speculation, aka ‘Windows ARM Information Disclosure Vulnerability’.
CWE-203
CVE-2020-14145
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
CVE-2020-13998
** UNSUPPORTED WHEN ASSIGNED ** Citrix XenApp 6.5, when 2FA is enabled, allows a remote unauthenticated attacker to ascertain whether a user exists on the server, because the 2FA error page only occurs after a valid username is entered. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2020-14002
PuTTY 0.68 through 0.73 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client).
CVE-2020-13844
Arm Armv8-A core implementations utilizing speculative execution past unconditional changes in control flow may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka “straight-line speculation.”
CVE-2020-13413
An issue was discovered in Aviatrix Controller before 5.4.1204. There is a Observable Response Discrepancy from the API, which makes it easier to perform user enumeration via brute force.
