|Gentoo Linux Security Advisory
Title: Net::DNS: Multiple vulnerabilities (GLSA 200708-06)
Date: August 11, 2007
Multiple vulnerabilities have been discovered in the Net::DNS Perl module,
allowing for a Denial of Service and a cache poisoning attack.
Net::DNS is a Perl implementation of a DNS resolver.
Vulnerable: < 0.60
Unaffected: >= 0.60
Architectures: All supported architectures
hjp discovered an error when handling DNS query IDs which make them
partially predictable. Steffen Ullrich discovered an error in the
dn_expand() function which could lead to an endless loop.
A remote attacker could send a specially crafted DNS request to the
server which could result in a Denial of Service with an infinite
recursion, or perform a cache poisoning attack.
There is no known workaround at this time.
All Net::DNS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-perl/Net-DNS-0.60"
