Security

Safe configuration of DNS

A group called The Measurement Factory has put out a press release to call attention to a recent survey of DNS servers. It seems that, according to TMF, the majority of publicly-available nameservers are configured incorrectly, and are vulnerable to denial of service and pharming attacks. In most cases, fixing the problems is a relatively straightforward operation.

Pharming refers to the use of cache poisoning attacks to hijack a domain name. If an attacker can convince your nameserver to return a bogus address for a known domain, your attempts to access a bank or other online financial-related site can be redirected to a malicious site. Many users have learned to enter domains for financial sites themselves, rather than, say, clicking on a random link which showed up in their mailbox. A pharming attack, however, can lead to the same result as a successful phish: account names, passwords, and credit card numbers can be captured.

So what are all of those DNS administrators doing wrong? The biggest problem, according to TMF, is that publicly-available nameservers are configured to perform recursive lookups for anybody who asks. If an attacker can request an arbitrary, recursive lookup, that attacker can get the target nameserver to contact - and accept data from - a malicious server. The malicious server can pass back incorrect information, which the target server may then cache and return to users. The solution in this case is to limit recursive queries to internal hosts; with bind, the allow-recursion option can be used to this effect.

The survey also notes that some 40% of sites on the net allow zone transfers to arbitrary sites. These transfers can disclose more information than one might like; they also represent a denial of service opportunity. Finally, the survey notes that a fair number of sites place their secondary servers on the same subnet as the primary, leading to obvious single point of failure issues.

Security issues with DNS servers have been relatively rare in recent times. A nameserver is only as secure as its configuration, however. Auditing nameservers for these issues in the near future might not be a bad idea.

New vulnerabilities

chkstat: information disclosure

Package(s):chkstat CVE #(s):
Created:October 24, 2005 Updated:October 25, 2005
Description: SUSE LINUX ships with three pre defined sets of permissions, 'easy', 'secure' and 'paranoid'. The chkstat program contained in the permissions package is used to set those permissions to the chosen level. Level 'easy' which is the default allows some world writeable directories. /usr/src/packages/RPMS and subdirectories is among them. To prevent users from playing tricks in there e.g. linking to /etc/shadow chkstat doesn't touch symlinks or files with an hardlink count != 1.

Stefan Nordhausen discovered a way to trick this check. To gain access to e.g. /etc/shadow a malicious user has to place a hardlink to that file at a place that is modified by chkstat. chkstat will not touch the file because it has a hardlink count of two. However, if the administrator modifies the user database the original /etc/shadow gets deleted and replaced by a new one. That means the hardlink count of the file created by the malicious user drops to one. At this point chkstat will modify the file's permissions so anyone can read it. So it's technically impossible for chkstat to modify permissions of files in world writeable directories in a secure way.

httpd: off-by-one overflow and cross-site scripting

Package(s):apache httpd CVE #(s):CAN-2005-1268 CAN-2005-2088
Created:July 25, 2005 Updated:November 7, 2005
Description: Watchfire reported a flaw that occurred when using the Apache server as an HTTP proxy. A remote attacker could send an HTTP request with both a "Transfer-Encoding: chunked" header and a "Content-Length" header. This caused Apache to incorrectly handle and forward the body of the request in a way that the receiving server processes it as a separate HTTP request. This could allow the bypass of Web application firewall protection or lead to cross-site scripting (XSS) attacks.

Marc Stern reported an off-by-one overflow in the mod_ssl CRL verification callback. In order to exploit this issue the Apache server would need to be configured to use a malicious certificate revocation list (CRL).

libgd2: buffer overflows in PNG handling

Package(s):libgd2 CVE #(s):CAN-2004-0990 CAN-2004-0941
Created:October 29, 2004 Updated:June 28, 2006
Description: Several buffer overflows have been discovered in libgd's PNG handling functions.
If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PHP. One possible target would be a PHP driven photo website that lets users upload images. Therefore this vulnerability might lead to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function.

libnet-ssleay-perl: weakened cryptographic operations

Package(s):libnet-ssleay-perl CVE #(s):CAN-2005-0106
Created:May 3, 2005 Updated:January 27, 2006
Description: Javier Fernandez-Sanguino Pena discovered that this library used the file /tmp/entropy as a fallback entropy source if a proper source was not set in the environment variable EGD_PATH. This can potentially lead to weakened cryptographic operations if an attacker provides a /tmp/entropy file with known content.
