Security 10944 Published by 0

Three new security updates for Gentoo Linux are available:

PACKAGE : fnord

fnord 1.6 contained a buffer overrun in the CGI code. However, since the function does not return, this does not appear to be exploitable

PACKAGE : dhcp

The Internet Software Consortium (ISC) has discovered several buffer overflow vulnerabilities in their implementation of DHCP (ISC DHCPD). These vulnerabilities may allow remote attackers to execute arbitrary code on affected systems. At this time, we are not aware of any exploits.

PACKAGE : kde-2.2.x

In some instances KDE fails to properly quote parameters of instructions passed to a command shell for execution.

These parameters may incorporate data such as URLs, filenames and e-mail addresses, and this data may be provided remotely to a victim in an e-mail, a webpage or files on a network filesystem or other untrusted source.

MandrakeSoft has released the follow security updates for Mandrake Linux:

MDKSA-2003:007 : dhcp

Several potential vulnerabilities were detected by the ISC (Internet Software Consortium) in their dhcp server software. The vulnerabilities affect the minires library and may be exploitable as stack buffer overflows, which could lead to remote code execution. All Mandrake Linux users are encouraged to upgrade; only Mandrake Linux 8.0 came with dhcp 2.x and is not vulnerable.

MDKSA-2003:004-1 : kde

Multiple instances of improperly quoted shell command execution exist in KDE 2.x up to and including KDE 3.0.5. KDE fails to properly quote parameters of instructions passed to the shell for execution. These parameters may contain data such as filenames, URLs, email address, and so forth; this data may be provided remotely to a victim via email, web pages, files on a network filesystem, or other untrusted sources.

Two new security updates for Debian GNU/Linux has been released:

DSA-231-1 dhcp3 -- stack overflows
The Internet Software Consortium discoverd several vulnerabilities during an audit of the ISC DHCP Daemon. The vulnerabilities exist in error handling routines within the minires library and may be exploitable as stack overflows. This could allow a remote attacker to execute arbitrary code under the user id the dhcpd runs under, usually root. Other DHCP servers than dhcp3 doesn't seem to be affected.

A new security update for Debian GNU/Linux has been released

DSA-226-1 xpdf-i -- integer overflow
iDEFENSE discovered an integer overflow in the pdftops filter from the xpdf and xpdf-i packages that can be exploited to gain the privileges of the target user. This can lead to gaining unprivileged access to the 'lp' user if the pdftops program is part of the print filter.

For the current stable distribution (woody) xpdf-i is only a dummy package and the problem was fixed in xpdf already.

For the old stable distribution (potato) this problem has been fixed in version 0.90-8.1.

For the unstable distribution (sid) this problem has been fixed in version 2.01-2.
