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...

CVE-2026-84308 phpseclib — non-constant-time X25519 scalar multiplication permits full private-key recovery

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...

Amazon Linux 2023 : apr-util, apr-util-devel, apr-util-ldap (ALAS2023-2026-2115)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2115 advisory. APR-util versions 1.6.3 and earlier function aprpasswordvalidate was not constant-time with regards to hashes or passwords comparisons, potentially leaking their content via a side channel...

Amazon Linux 2 : apr-util, --advisory ALAS2-2026-3892 (ALAS-2026-3892)

The version of apr-util installed on the remote host is prior to 1.6.5-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3892 advisory. APR-util versions 1.6.3 and earlier function aprpasswordvalidate was not constant-time with regards to hashes or password...

Important: apr-util

Issue Overview: APR-util versions 1.6.3 and earlier function aprpasswordvalidate was not constant-time with regards to hashes or passwords comparisons, potentially leaking their content via a side channel timing attack particularly on platforms without crypt such as Windows, BeOS, NetWare, or...

Unity Linux 20.1070e Security Update: nss (UTSA-2026-030724)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-030724 advisory. The NSS code used for checking PKCS1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well...

CVE-2026-55785

free5GC is an open-source implementation of the 5G core network. Prior to 1.4.5, the AUSF component performs cryptographic authentication comparisons in internal/sbi/processor/ueauthentication.go with ordinary equality helpers. Auth5gAkaComfirmRequestProcedure compares RES and XRES with...

GHSA-FP46-6VFW-GC9C free5GC AUSF uses non-constant-time authentication comparisons and logs XRES* in 5G-AKA

Summary The AUSF component of free5GC compares authentication response values with normal Go equality helpers instead of constant-time cryptographic comparison functions. Two authentication flows are affected in internal/sbi/processor/ueauthentication.go: 1. 5G-AKA confirmation compares RES and...
