Three locale-related vulnerabilities with glibc 2.1.3 were recently reported on BugTraq. These vulnerabilities could allow local users to gain root access.

Recently two problems have been found in the glibc suite, which could be used to trick setuid applications to run arbitrary code.

A format string bug was recently discovered in screen which can be used to gain elevated privilages if screen is setuid. Debian 2.1 (slink) did ship screen setuid and the exploit can be used to gain root privilages. In Debian 2.2 (potato) screen is not setuid, and is not vulnerable to a root exploit. screen is, however, setgid utmp in Debian 2.2 (potato) and we recommend upgrading.

A root exploit was found in the /usr/bin/suidperl5.6.0 program that shipped with the Slackware 7.1 perl.tgz package.

Existing Netscape Communicator/Navigator packages contain the following vulnerabilities:

Several bugs were discovered in glibc which could allow local users to gain root privileges.

The version of X-Chat that was distributed with Debian GNU/Linux 2.2 has a vulnerability in the URL handling code: when a user clicks on a URL X-Chat will start netscape to view its target. However it did not check the URL for shell metacharacters, and this could be abused to trick xchat into executing arbitraty commands.

The updated version of ntop (1.2a7-10) that was released on August 5 was found to still be insecure: it was still exploitable using buffer overflows. Using this technique it was possible to run arbitrary code as the user who ran ntop in web mode.

Updated usermode packages are now available for Red Hat Linux 6.0, 6.1, and 6.

Due to US-American export restrictions for cryptographical software, we are unable to provide update packages on our US ftp server http://ftp.suse.com. Instead, the packages can be found on http://ftp.suse.de. For

The legal issues have been resolved: Here are the links to download the SuSE Netscape update packages from our US-American ftp server:

A new XChat package is available that fixes a possible security hole.

Two security problems exist in the netscape package as shipped with SuSE Linux distributions. a) Improper verification in Netscape's jpeg processing code can lead to a buffer overflow where data read from the network can overwrite memory. As a result, arbitrary code from a remote origin could be executed. The attack is particularly dangerous since it can penetrate firewall setups. Netscape version 4.74 fixes (fixed) this vulnerability. b) Due to an error in the java implementation in Netscape, it is possible for an attacker to view files and directories with the priviledges of the user running Netscape if the user visits a malisciously crafted webpage. This issue is known as "Brown Orifice" and requires the user to have Java enabled in her browser configuration. Again, this attack can penetrate firewall setups. See http://www.brumleve.com/BrownOrifice for details.

On versions of Zope prior to 2.2.1 it was possible for a user with the ability to edit DTML to gain unauthorized access to extra roles during a request. A fix was previously announced in the Debian zope package 2.1.6-5.1, but that package did not fully address the issue and has been superseded by this announcement. More information is available at http://www.zope.org/Products/Zope/Hotfix_2000-08-17/security_alert

New Netscape packages are available to fix a serious security problem with Java. It is recommended that all netscape users update to the new packages. Users of Red Hat Linux 6.0 and 6.1 should use the packages for Red Hat Linux 6.

Updated perl and mailx package are now available which fix a potential exploit made possible by incorrect assumptions made in suidperl. This advisory contains additional instructions for installing the necessary updates.

Vulnerabilities exist with all Zope-

There is a format string bug in all versions of xlockmore/xlockmore-gl. Debian 2.1 (slink) installs xlock setgid by default, and this exploit can be used to gain read access to the shadow file. We recommend upgrading immediately.
