Mandrake Linux Security Advisory : gnutls (MDKSA-2006:166)

Medium Nessus Plugin ID 24552


The remote Mandrake Linux host is missing one or more security updates.


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.

The provided packages have been patched to correct this issues.


Update the affected packages.
