An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating optimisations were possible in the accumulator variable in hmac.compare_digest.

In Paramiko before 2.10.1, a race condition (between creation and chmod) in the write_private_key_file function could allow unauthorized information disclosure.

A timing condition in Harbor 2.6.x and below, Harbor 2.7.2 and below,  Harbor 2.8.2 and below, and Harbor 1.10.17 and below allows an attacker with network access to create jobs/stop job tasks and retrieve job task information.

It was found that the implementation of the GTNSubjectCreatingInterceptor class in gatein-wsrp was not thread safe. For a specific WSRP endpoint, under high-concurrency scenarios or scenarios where SOAP messages take long to execute, it was possible for an unauthenticated remote attacker to gain privileged information if WS-Security is enabled for the WSRP Consumer, and the endpoint in question is being used by a privileged user. This affects JBoss Portal 6.2.0.

Bouncy Castle BC Java before 1.66, BC C# .NET before 1.8.7, BC-FJA before 1.0.1.2, 1.0.2.1, and BC-FNA before 1.0.1.1 have a timing issue within the EC math library that can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures.

A race condition flaw was found in the response headers Elasticsearch versions before 7.2.1 and 6.8.2 returns to a request. On a system with multiple users submitting requests, it could be possible for an attacker to gain access to response header containing sensitive data from another user.

Race condition in the XMPP library in Smack before 4.1.9, when the SecurityMode.required TLS setting has been set, allows man-in-the-middle attackers to bypass TLS protections and trigger use of cleartext for client authentication by stripping the "starttls" feature from a server response.

A remote arbitrary file read vulnerability was discovered in some Aruba Instant Access Point (IAP) products in version(s): Aruba Instant 6.5.x: 6.5.4.18 and below; Aruba Instant 8.3.x: 8.3.0.14 and below; Aruba Instant 8.5.x: 8.5.0.11 and below; Aruba Instant 8.6.x: 8.6.0.7 and below; Aruba Instant 8.7.x: 8.7.1.1 and below. Aruba has released patches for Aruba Instant that address this security vulnerability.
