Description

Peter Johannes Holzer discovered that the Net::DNS Perl module had predictable sequence numbers. This could allow remote attackers to carry out DNS spoofing, leading to possible man-in-the-middle attacks. (CVE-2007-3377)

Steffen Ullrich discovered that the Net::DNS Perl module did not correctly detect recursive compressed responses. A remote attacker could send a specially crafted packet, causing applications using Net::DNS to crash or monopolize CPU resources, leading to a denial of service. (CVE-2007-3409).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
