Mandrake Linux Security Advisory : perl-Net-DNS (MDKSA-2007:146)

Medium Nessus Plugin ID 25721


The remote Mandrake Linux host is missing a security update.


A flaw was discovered in the perl Net::DNS module in the way it generated the ID field in a DNS query. Because it is so predictable, a remote attacker could exploit this to return invalid DNS data (CVE-2007-3377).

A denial of service vulnerability was found in how Net::DNS parsed certain DNS requests. A malformed response to a DNS request could cause the application using Net::DNS to crash or stop responding (CVE-2007-3409).

The updated packages have been patched to prevent these issues.


Update the affected perl-Net-DNS package.
