"While testing for Oracle vulnerabilities, Mark Litchfield discovered a denial of service attack for Apache on Windows. Investigation by the Apache Software Foundation showed that this issue has a wider scope, which on some platforms results in a denial of service vulnerability, while on some other platforms presents a potential a remote exploit vulnerability."

ISS and the OpenSSH team just released advisories concerning the OpenSSH vulnerability.

This advisory is an update to DSA-134-2: the changes mainly deal with packaging issues; if you have already successfully installed an openssh package from a previous DSA-134 advisory you may disregard this message.

There's a new vulnerabilty in the OpenSSH daemon, of which we were notified yesterday.

This advisory is an update to DSA-134-1: some extra information is provided on broken or changed functionality in this new release and packages for Debian GNU/Linux 2.2/potato are now available.

There's a new vulnerabiltiy in the OpenSSH daemon. The OpenSSH/OpenBSD team does not release any details concerning this issue, except:

Details of an upcoming OpenSSH vulnerability will be published early next week. According to the OpenSSH team, this remote vulnerability cannot be exploited when sshd is running with privilege separation. The priv separation code is significantly improved in version 3.3 of OpenSSH which was released on June 21st. Unfortunately, there are some known problems with this release; compression does not work on all operating systems and the PAM support has not been completed. The OpenSSH team encourages everyone to upgrade to version 3.3 immediately and enable privilege separation.

Theo de Raadt announced that the OpenBSD team is working with ISS on a remote exploit for OpenSSH (a free implementation of the Secure SHell protocol). They are refusing to provide any details on the vulnerability but instead are advising everyone to upgrade to the latest release, version 3.3.

[ Please note that this advisory supersedes the previous MDKSA-2002:039 and MDKSA-2002:039-1 advisories. ] MandrakeSoft is urging all users of Mandrake Linux to update their Apache installations immediately. What was previously thought to have been a DoS-only condition has now been proven to be more than that; exploitable conditions have been discovered on both 32bit and 64bit platforms.

A Denial of Service attack was discovered by Mark Litchfield in the Apache webserver. As well, while investigating this problem, the Apache Software Foundation discovered that the code for handling invalid requests that use chunked encoding may also allow arbitrary code to be executed on 64bit architectures. All versions of Apache prior to 1.3.26 and 2.0.37 are vulnerable to this problem. This update provides patched versions of Apache for the remaining supported Mandrake Linux versions.

All versions of Apache prior to 1.3.26 and 2.0.37 are vulnerable to this problem. A patched version of Apache is currently available for Single Network Firewall 7.2, with patched versions of Apache soon to be available for the other supported Mandrake Linux versions.

The Apache Web server contains a security vulnerability which can be used to launch a denial of service attack, or in some cases, allow remote code execution.

There is a bug in the way the Apache web server handles HTTP requests that use "chunked mode". Chunked mode is a HTTP 1.1 feature that allows a client to send data as a sequence of chunks rather than en bloc. This is useful if it doesn't know the overall length of the content at the time it starts transmitting.

The DSA-131-1 advisory for the Apache chunk handling vulnerability contained an error and was missing some essential information:

The LPRng print spooler, as shipped in Red Hat Linux 7.x, accepts all remote print jobs by default.

Updated mailman packages are now available for Red Hat Linux 7.2 and 7.3. These updates resolve a cross-site scripting vulnerability present in versions of Mailman prior to
