Package        : libnet-dns-perl
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-3377 CVE-2007-3409 CVE-2007-6341
Debian Bug     : 457445

Several remote vulnerabilities have been discovered in libnet-dns-perl.
The Common Vulnerabilities and Exposures project identifies the
following problems:

It was discovered that libnet-dns-perl generates very weak transaction
IDs when sending queries (CVE-2007-3377).  This update switches
transaction ID generation to the Perl random generator, making
prediction attacks more difficult.

Compression loops in domain names resulted in an infinite loop in the
domain name expander written in Perl (CVE-2007-3409).  The Debian
package uses an expander written in C by default, but this vulnerability
has been addressed nevertheless.

Decoding malformed A records could lead to a crash (via an uncaught
Perl exception) of certain applications using libnet-dns-perl
(CVE-2007-6341).

For the stable distribution (etch), these problems have been fixed in
version 0.59-1etch1.

For the old stable distribution (sarge), these problems have been fixed in
version 0.48-1sarge1.

We recommend that you upgrade your libnet-dns-perl package.
