Security Bulletin: Multiple vulnerabilities in IBM Tivoli Network Manager IP Edition

Summary Multiple vulnerabilities were addressed in IBM Tivoli Network Manager IP Edition 4.2.0.25 IF1 Vulnerability Details CVEID:CVE-2026-17508 DESCRIPTION: In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the...

CVE-2026-17508

A flaw was found in Bouncy Castle. Several password-based key derivation functions KDF process cost parameters directly from untrusted input without enforcing upper bounds. An attacker can exploit this vulnerability by supplying crafted input containing excessively high cost parameters, forcing t...

CVE-2026-17508 Password-based KDF cost parameters honoured unbounded from untrusted input across the remaining PBE entry points

In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before any password or integrity check could...

CVE-2026-81721 openssl_encrypt before 1.4.9 Denial of Service via KDF

opensslencrypt before 1.4.9 fails to validate KDF cost parameters in encrypted file metadata and keystore headers, allowing attackers to trigger unbounded memory allocation. Attackers can craft malicious encrypted files declaring arbitrarily large Argon2, scrypt, or balloon KDF parameters to...

CVE-2026-81721

openssl_encrypt before 1.4.9 fails to validate KDF cost parameters (Argon2, scrypt, or balloon) in encrypted file metadata and keystore headers. An unauthenticated attacker over the network can craft a malicious encrypted file declaring arbitrarily large KDF parameters, triggering unbounded memor...

📄 PHP 8.5.7 levenshtein() Signed-Integer Overflow

The levenshtein function calculates the Levenshtein distance between two strings, optionally accepting custom costs for insertion, replacement, and deletion operations. In PHP version 8.5.7, the implementation lacks proper bounds checking for these cost parameters. PHP 8.5.7 levenshtein...
