Where are the kernel updates?
On April 5, Florian Weimer sent a note to the linux-kernel mailing list describing a hashing vulnerability in the 2.4 kernel. His assessment:
This problem was also described on this page last week.
We are, in other words, going on two months since this vulnerability was publicly disclosed. A quick look at the LWN Vulnerability Database entry for this problem, however, shows that only two distributors (EnGarde and Red Hat) have updated their kernels to close this hole. So all of the other distributors, many of which have a very good history of quick response to security problems, are leaving their users exposed on this one.
This vulnerability may seem less urgent because it cannot be used to gain root access to a target machine. It can, however, be used to take a system off the net. It allows a remote attacker to obtain the results of a distributed denial of service attack without that attacker having to arrange the "distributed" part. It is a serious problem which will certainly be exploited, with unpleasant results. The distributors owe their users a fix.
New vulnerabilities
Apache 2 - denial of service

| Created: | May 28, 2003 | Updated: | June 16, 2003 | ||||||||||||||||||
| Description: | A new set of denial of service vulnerabilities has been found in Apache versions 2.0 through 2.0.45. The potential for a remote code exploit apparently exists as well. See the Apache 2.0.46 announcement for more information. | ||||||||||||||||||||

CUPS: vulnerability in the CUPS IPP implementation
| Package(s): | cups | CVE #(s): | CAN-2003-0195 | ||||||||||||||||||||||||
| Created: | May 27, 2003 | Updated: | July 22, 2003 | ||||||||||||||||||||||||
| Description: | Phil D'Amore of Red Hat discovered a vulnerability in the CUPS IPP (Internet Printing Protocol) implementation. The IPP implementation is single-threaded, which means only one request can be serviced at a time. An attacker could make a partial request that does not time out and therefore creates a denial of service. In order to exploit this bug, an attacker must have the ability to make a TCP connection to the IPP port (by default 631). | ||||||||||||||||||||||||||

| Created: | May 27, 2003 | Updated: | August 12, 2004 | |||
| Description: | Some some vulnerabilities exsist in the Nessus NASL scripting engine. To exploit these flaws, an attacker would need to have a valid Nessus account as well as the ability to upload arbitrary Nessus plugins in the Nessus server (this option is disabled by default) or he/she would need to trick a user somehow into running a specially crafted nasl script.

remote attackers to execute arbitrary commands in certain circumstances.
This is due to the usage of mailx as default mailer which allows commands

| Created: | July 8, 2002 | Updated: | October 1, 2003 | |||||||||||||||||||||||||||||||||||||||||||||
| Description: | The BIND 4.9.8-OW2 patch and BIND 4.9.9 release (and thus 4.9.9-OW1)
include fixes for a libc related vulnerability which does not
affect Linux. Updates from
the Internet Software Consortium (ISC)
are available from here.
No release or branch of Openwall GNU/*/Linux (Owl) is known to be
affected, due to Olaf Kirch's fixes for this problem getting into the
GNU C library more than two years ago.
Unfortunatly that does not mean that Linux systems are not vulnerable. Similar code, without Olaf Firch's fixes, is in the glibc getnetbyXXX functions. These functions are described in the SuSE alert as " used by very few applications only, such as ifconfig and ifuser, which makes exploits less likely."

Potential remote root exploit in glibc

exploited to gain unauthorized root access to software linking to glibc.
Updating as soon as practical is a good idea.
Because SunRPC-derived XDR libraries are used by a variety of vendors in a variety of applications, this defect may lead to a number of differing security problems. Exploiting this vulnerability will lead to denial of service, execution of arbitrary code, or the disclosure of sensitive information.

VU#738331)
The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, uses the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash). | |||||||||||

| Created: | April 10, 2003 | Updated: | June 30, 2003 | ||||||||||||||||||||||||||||||||||||
| Description: | The KDE Security team has issued an advisory
on a vulnerability present in all versions of KDE that allow a remote
attacker to execute arbitrary commands under your account. KDE 3.0.5b and
KDE 3.1.1a have been released to address this problem. For KDE 2.2.2
patches to the KDE 2.2.2 sources have been made available.
KDE uses Ghostscript software for processing of PostScript (PS) and PDF files in a way that allows for the execution of arbitrary commands that can be contained in such files. An attacker can prepare a malicious PostScript or PDF file which will provide the attacker with access to the victim's account and privileges when the victim opens this malicious file for viewing or when the victim browses a directory containing such malicious file and has file previews enabled. An attacker can provide malicious files remotely to a victim in an e-mail, as part of a webpage, via an ftp server and possible other means. | ||||||||||||||||||||||||||||||||||||||

| Created: | March 18, 2003 | Updated: | May 22, 2003 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Description: | David Brumley and Dan Boneh of Stanford University have researched and
documented a timing attack on OpenSSL which allows local and remote
attackers to extract the RSA private key of a server. The OpenSSL RSA
implementation is generally vulnerable to these type of attacks unless RSA
blinding has been turned on. See this
paper (pdf format) for additional details.
Typically, RSA blinding is not enabled by OpenSSL based applications, mainly because it is not obvious how to do so when using OpenSSL to provide SSL/TLS. This problem affects mostly all applications using OpenSSL and have to be rebuilded against the fixed OpenSSL version (where RSA blinding is now enabled by default) or have to enable RSA blinding explicitly their own. The performance impact of RSA blinding appears to be small (a few percent only) and the RSA functionality is still fully compatible. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0147 to the problem. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
