Security Bulletin: Multiple vulnerabilities in IBM Tivoli Monitoring affect IBM Cloud Pak System

Summary Multiple vulnerabilities in IBM Tivoli Monitoring affect IBM Cloud Pak System. Vulnerability Details CVEID:CVE-2024-35154 DESCRIPTION: IBM WebSphere Application Server 8.5 and 9.0 could allow a remote authenticated attacker, who has authorized access to the administrative console, to...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to ambiguity in the HMAC validation of signed URLs used for artifact access. An attacker can gain unauthorized read access to artifacts across repositories and write to upload-state...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the cookie parsing process. An attacker can cause unauthorized cookies to be set and transmitted to unrelated third-party domains by crafting HTTP responses that exploit improper doma...

EUVD-2026-41440

Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

DEBIAN-CVE-2026-50721

Libreswan, via the function RSAauthenticatehashsignaturerawrsa, did not correctly verify the length of the authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS 1 RSA Encryption as per RFC 2313. A remote attacker can use a variation on the Bleichenbacher attack to for...

CVE-2026-50721

CVE-2026-50721 concerns Libreswan where the function RSA_authenticate_hash_signature_raw_rsa() does not properly verify the authentication hash length when the SIG payload of an IKEv1 packet is encoded using PKCS#1 RSA Encryption per RFC 2313. This enables a remote attacker to leverage a Bleichen...

CVE-2026-50722

Libreswan is affected by CVE-2026-50722 through RSA_authenticate_hash_signature_pkcs1_1_5_rsa, which fails to properly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload uses RSASSA-PKCS1-v1_5 (RFC 8017). This enables a remote attacker to perform a Bleichenbacher-like variati...

zebrad has consensus divergence via P2SH sigop undercount in pure-Rust disabled-opcode parser

Am I affected You are affected if: 1. You run any version of zebrad up to and including v4.4.1. 2. Your node validates blocks on mainnet, testnet, or any network where both Zebra and zcashd nodes participate. All default configurations are affected. No feature flags, non-default settings, or...
