CVE-2026-5598: Covert Timing Channel

Covert timing channel vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA core on all core modules. This vulnerability is associated with program files FrodoEngine.Java. This issue affects BC-JAVA: from 1.71 before 1.80.2, from 1.81 before 1.81.1, from 1.82 before 1.84...

Oxia affected by server crash via race condition in session heartbeat handling

Summary A race condition between session heartbeat processing and session closure can cause the server to panic with send on closed channel. The heartbeat method uses a blocking channel send while holding a mutex, and under specific timing with concurrent close calls, this can lead to either a...

Crypt::SecretBuffer versions before 0.019 for Perl is suseceptible to timing attacks. For example, if Crypt::SecretBuffer was used to store and compare plaintext passwords, then discrepencies in timing could be used to guess the secret password...

Tamper-Proofing with Self-Modifying Code

Classical computability theory tells us that self-modifying code SMC on a deterministic universal Turing machine can be simulated by non-SMC code on the same model. That abstraction, however, omits the external timing inputs, concurrency, and microarchitectural state that dominate practical...

Important: amazon-efs-utils

Issue Overview: time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used...

CVE-2026-5086

The Crypt::SecretBuffer Perl module (developed by NERDVANA) is vulnerable to timing attacks in versions prior to 0.019 . If the module is used to store and compare plaintext passwords, an attacker can exploit discrepancies in processing time to guess secret passwords. A proof-of-concept was publi...

Note Mark: Username Enumeration via Login Endpoint Timing Side-Channel

Summary A timing side-channel in the login endpoint allows unauthenticated attackers to determine whether a username exists by measuring response time differences. Requests for valid usernames take noticeably longer because the server performs bcrypt password verification, while requests for...
