Debian Security Advisory

DSA-1515-1 libnet-dns-perl -- several vulnerabilities

Date Reported:
11 Mar 2008
Affected Packages:
libnet-dns-perl
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 457445.
In Mitre's CVE dictionary: CVE-2007-3377, CVE-2007-3409, CVE-2007-6341.
More information:

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

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

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

Fixed in:

Debian GNU/Linux 3.1 (sarge)
