CVE-2026-59276

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

ssh-enum

ssh-enum CVE-2016-6210 统计验证研究 对 OpenSSH 用户名枚举的可重现再调查，基于统计分析。 本项目重新调查了 CVE-2016-6210 ，一个已知的 OpenSSH 定时侧信道漏洞，旨在确定其在现代 Ubuntu Server 使用默认 PAM 配置时是否仍然可观测。 项目并未假设已公开的行为仍然适用，而是通过手动探测、Hydra 和 Metasploit 收集认证计时测量值，并运用 韦尔奇的 t 检验 和 科恩的 d 值 来区分真实的计时信号与测量噪声。 研究发现，在测试的默认配置下 没有统计上显著的计时差异...

DEBIAN-CVE-2026-84308

phpseclib is a PHP secure communications library. Prior to 3.0.57 and 4.0.1, pure-PHP X25519 scalar multiplication in phpseclib/Math/PrimeField/Integer.php performs data-dependent conditional modular reductions in add and subtract. During the Montgomery ladder in...

CVE-2026-84308

phpseclib , a PHP secure communications library, has a non-constant-time X25519 scalar multiplication flaw in versions prior to 3.0.57 and 4.0.1 . The root cause is data-dependent conditional modular reductions in the pure-PHP implementation (Math/PrimeField/Integer.php), which leak per-step timi...
