Overview

CVE-2006-4790 is a medium-severity vulnerability affecting gnu gnutls. It was published on September 14, 2006 and has a CVSS 2.0 base score of 5.0 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 5.0, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

verify.c in GnuTLS before 1.4.4, when using an RSA key with exponent 3, does not properly handle excess data in the digestAlgorithm.parameters field when generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents GnuTLS from correctly verifying X.509 and other certificates that use PKCS, a variant of CVE-2006-4339.

Remediation

Check the references section for vendor advisories and patches from gnu. Update gnutls to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
