CVE-2024-23953

Description

Use of Arrays.equals() in LlapSignerImpl inApache Hive to compare message signaturesallows attacker to forge a valid signature for an arbitrary message byte by byte. The attacker should be an authorized user of the product to perform this attack.Users are recommended to upgrade to version 4.0.0, which fixes this issue.The problem occurs when an application doesnt use a constant-time algorithm for validating a signature.The method Arrays.equals()returns falseright away when it sees that one of the inputs bytes are different. It means that the comparison time depends on the contents of the arrays. This little thing may allow an attacker to forge a valid signature for an arbitrary message byte by byte.So it might allow malicious users to submit splits/work with selected signatures to LLAP without running as a privileged user, potentially leading to DDoS attack.More details in the reference section.
