A recent (fall 2000) security fix to cron introduced an error in giving up privileges before invoking the editor. A malicious user could easily gain root access.

The sgmltool programs ("sgml2html" and others) are used to convert SGML-files into various other formats.

Updated mount packages fixing a potential security problem are available.

Updated kdelibs packages fixing a security problem, some memory leaks and some minor bugs are available.

The nedit (Nirvana editor) package as shipped in the non-free section accompanying Debian GNU/Linux 2.2/potato had a bug in its printing code: when printing text it would create a temporary file with the to be printed text and pass that on to the print system. The temporary file was not created safely, which could be exploited by an attacked to make nedit overwrite arbitrary files.

This is an addition to DSA 043-1 which fixes several vulnerabilities in Zope. Something went wrong so it has to be corrected. The previous security release 2.1.6-7 has two severe problems:

An updated gftp package is available for Red Hat Linux 6.2 and 7.1. This package contains an upgrade to gftp version

Daniel Kobras has discovered and fixed a problem in sendfiled which caused the daemon not to drop privileges as expected when sendnig notification mails. Exploiting this a local user can easily make it execute arbitrary code under root privileges.

Florian Wesch has discovered a problem (reported to bugtraq) with the way how Netscape handles comments in GIF files. The Netscape browser does not escape the GIF file comment in the image information page. This allows javascript execution in the "about:" protocol and can for example be used to upload the History (about:global) to a webserver, thus leaking private information. This problem has been fixed upstream in Netscape 4.77. Since we haven't received sourcecode for these packages they are not part of the Debian GNU/Linux distribution but are packaged up as `.deb' files for a convenient installation.

Updated mgetty packages are now available for Red Hat Linux 6.2 and 7.x. These packages fix packaging errors present in previous versions.

The HylaFax program hfaxd(8c) implements the server part of the HylaFax package. It is started either by inetd(8) or runs in standalone mode. hfaxd(8c) offers three different protocols to process fax jobs. When hfaxd(8c) tries to change to it's queue directory and fails, it prints an error message via syslog by directly passing user supplied data as format string. As long as hfaxd(8c) is installed setuid root, this behavior could be exploited to gain root access locally.

Colin Phipps and Daniel Kobras discovered and fixed several serious bugs in the saft daemon `sendfiled' which caused it to drop privileges incorrectly. Exploiting this a local user can easily make it execute arbitrary code under root privileges.

A security hole has been found that does not affect the default configuration of Red Hat Linux, but can affect some custom configurations of Red Hat Linux 7.1 only. The bug is specific to the Linux

The Nirvana Editor, NEdit, is a GUI-style text editor based on popular Macintosh and MS Windows editors. When printing a whole text or selected parts of a text, nedit(1) creates a temporary file in an insecure manner. This behavior could be exploited to gain access to other users privileges, even root.

The setuid application sudo(8) allows a user to execute commands under the privileges of another user (including root). sudo(8) previous to version 1.6.3p6 is vulnerable by a buffer overflow in it's logging code, which could lead to local root compromise.

The updated exuberant-ctags that was mentioned in DSA-046-1 was unfortunately compiled incorrectly: the stable chroot we used turned out to be running unstable instead.

The updated samba packages that were mentioned in DSA-048-1 were unfortunately compiled incorrectly: the stable chroot we used turned out to be running unstable instead.

Megyer Laszlo report on Bugtraq that the cfingerd Debian as distributed with Debian GNU/Linux 2.2 was not careful in its logging code. By combining this with an off-by-one error in the code that copied the username from an ident response cfingerd could exploited by a remote user. Since cfingerd does not drop its root privileges until after it has determined which user to finger an attacker can gain root privileges.

Marcus Meissner discovered that samba was not creating temporary files safely in two places:
