EulerOS 2.0 SP9 : dhcp (EulerOS-SA-2023-2610)

According to the versions of the dhcp package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively...

Important: python-ecdsa

Issue Overview: An error-handling flaw was found in python-ecdsa before version 0.13.3. During signature decoding, malformed DER signatures could raise unexpected exceptions or no exceptions at all, which could lead to a denial of service. CVE-2019-14853 A flaw was found in all python-ecdsa...

Inaccurate implementation of ECDSA creates signature malleability

Lines of code Vulnerability details Impact The ecrecover function is an inherent cryptographic function within Solidity which enables the retrieval of the signer's address messages which have been signed with their private key. Of course, this is very important when it comes to verifying the...

Signature malleability not protected against

Lines of code Vulnerability details Impact A signature should never be included into a signed message hash to check if previously messages have been processed by the contract. See reference: Proof of Concept Provide direct links to all referenced code in GitHub. Add screenshots, logs, or any othe...

EulerOS Virtualization 3.0.6.6 : bind (EulerOS-SA-2023-2404)

According to the versions of the bind packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance,...

USN-6239-1: ECDSA Util vulnerability

It was discovered that ECDSA Util did not properly verify certain signature values. An attacker could possibly use this issue to bypass signature verification...

Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS : ECDSA Util vulnerability (USN-6239-1)

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6239-1 advisory. It was discovered that ECDSA Util did not properly verify certain signature values. An attacker could possibly use this issue ...

ALSA-2023:3722 Moderate: openssl security and bug fix update

OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength general-purpose cryptography library. Security Fixes: openssl: Possible DoS translating ASN.1 object identifiers CVE-2023-2650 openssl: Denial of service by...

Power LED Side-Channel Attack

This is a clever new side-channel attack: The first attack uses an Internet-connected surveillance camera to take a high-speed video of the power LED on a smart card reader­--or of an attached peripheral device--­during cryptographic operations. This technique allowed the researchers to pull a...

The signature "V" length is not checked in castApprovalBySig, CastDisapprovalBySig & createActionBySig

Lines of code Vulnerability details Impact The length of the "v" value in the signatures is not checked. V must correspond according to ECDSA principles values of either 27 or 28. Not checking this will result in an attacker crafting a malicious v value and bypassing any checks, withdrawing funds...

[ H ] No Validation checks for "v" signature in castApprovalBySig

Lines of code Vulnerability details Impact V must correspond according to ECDSA principles values of either 27 or 28. Not checking this will result in an attacker crafting a malicious v value and bypassing any checks, withdrawing funds or accessing the function maliciously. Proof of Concept Craft...

Signature malleability in createActionBySig allow an attacker to replicate an attack

Lines of code Vulnerability details Overview The createActionBySig is part of a family of functions that can be called by signature. This functionality is shared with castApprovalBySig and castDisapprovalBySig. However, the last two functions rely on the preCastAssertion function that revert on...
