Insecure Signature Validation

SOGo is using insecure signature validation. It does not validate the signatures of any SAML assertions it receives. Any actor with network access to the deployment could impersonate users when SAML is the authentication method...

Updated grub2 packages fix security vulnerabilities

All CVEs below are against the SecureBoot functionality in GRUB2. We do not ship this as part of Mageia. Therefore, we ship an updated grub2 package to 2.06 for Mageia 8 fixing upstream bugfixes. A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and...

Linux kernel 数据伪造问题漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in versions of the Linux kernel prior to 5.12.14, which stems from the fact that the kernel's module.c incorrectly handles signature validation...

SUSE SLES11 Security Update : grub2 (SUSE-SU-2020:14461-1)

The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2020:14461-1 advisory. - GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the...

DEBIAN-CVE-2021-33054

SOGo 2.x before 2.4.1 and 3.x through 5.x before 5.1.1 does not validate the signatures of any SAML assertions it receives. Any actor with network access to the deployment could impersonate users when SAML is the authentication method. Only versions after 2.0.5a are affected...

CVE-2021-33054

CVE-2021-33054 affects SOGo 2.x (before 2.4.1) and 3.x–5.x (before 5.1.1); the issue is that SOGo does not validate signatures of any SAML assertions, allowing an attacker with network access to impersonate users via SAML authentication. The root cause is the lack of SAML signature validation. Pu...

GHSA-X5H4-9GQW-942J Improper Verification of Cryptographic Signature in aws-encryption-sdk

Impact This advisory addresses several LOW severity issues with streaming signed messages and restricting processing of certain types of invalid messages. This ESDK supports a streaming mode where callers may stream the plaintext of signed messages before the ECDSA signature is validated. In...

PT-2021-24353 · Amazon Web Services · Aws Encryption Sdk For Java

Name of the Vulnerable Software and Affected Versions: AWS Encryption SDK for Java versions 2.0.0 through 2.2.0 AWS Encryption SDK for Java versions less than 1.9.0 Description: The issue concerns the incorrect validation of some invalid ECDSA signatures. This affects the integrity of the...

CVE-2020-27847

A vulnerability exists in the SAML connector of the github.com/dexidp/dex library used to process SAML Signature Validation. This flaw allows an attacker to bypass SAML authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Thi...

CVE-2021-22160 Authentication with JWT allows use of “none”-algorithm

If Apache Pulsar is configured to authenticate clients using tokens based on JSON Web Tokens JWT, the signature of the token is not validated if the algorithm of the presented token is set to "none". This allows an attacker to connect to Pulsar instances as any user incl. admins...

GHSA-5684-G483-2249 Signature Validation Bypass

Impact Given a valid SAML Response, an attacker can potentially modify the document, bypassing signature validation in order to pass off the altered document as a signed one. This enables a variety of attacks, including users accessing accounts other than the one to which they authenticated in th...

Signature Validation Bypass

Impact An authentication bypass exists in the goxmldsig this library uses to determine if SAML assertions are genuine. An attacker could craft a SAML response that would appear to be valid but would not have been genuinely issued by the IDP. Patches Version 0.4.2 bumps the dependency which should...

GHSA-Q547-GMF8-8JR7 github.com/russellhaering/goxmldsig vulnerable to Signature Validation Bypass

Impact With a carefully crafted XML file, an attacker can completely bypass signature validation and pass off an altered file as a signed one. Patches A patch is available, all users of goxmldsig should upgrade to v1.1.0. For more information If you have any questions or comments about this...

Go JOSE Signature Validation Bypass

Go JOSE before 1.1.0 suffers from multiple signatures exploitation. The go-jose library supports messages with multiple signatures. However, when validating a signed message the API did not indicate which signature was valid, which could potentially lead to confusion. For example, users of the...
