3. Problem description:
Flaws have been found in the cookie path handling between a number of Web browsers and servers. The HTTP cookie standard allows a Web server supplying a cookie to a client to specify a subset of URLs on the origin server to which the cookie applies. Web servers such as Apache do not filter returned cookies and assume that the client will only send back cookies for requests that fall within the server-supplied subset of URLs. However, by supplying URLs that use path traversal (/../) and character encoding, it is possible to fool many browsers into sending a cookie to a path outside of the originally-specified subset. The Common Vulnerabilities and Exposures project has assigned the name CAN-2003-0592 to this issue.
iDEFENSE identified a vulnerability in the Opera web browser that could allow remote attackers to create or truncate arbitrary files. The KDE team has found two similar vulnerabilities that also exist in KDE. A flaw in the telnet URI handler may allow options to be passed to the telnet program, resulting in creation or replacement of files. An attacker could create a carefully crafted link such that when opened by a victim it creates or overwrites a file with the victim's permissions. A flaw in the mailto URI handler may allow options to be passed to the kmail program. These options could cause kmail to write to the file system or to run on a remote X display. An attacker could create a carefully crafted link in such a way that access may be obtained to run arbitrary code as the victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0411 to these issues.
Andrew Tuitt reported that versions of KDE up to and including 3.2.3 create temporary directories with predictable names. A local attacker could prevent KDE applications from functioning correctly, or overwrite files owned by other users by creating malicious symlinks. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-0689 to this issue.
WESTPOINT internet reconnaissance services has discovered that the KDE web browser Konqueror allows websites to set cookies for certain country specific secondary top level domains. An attacker within one of the affected domains could construct a cookie which would be sent to all other websites within the domain leading to a session fixation attack. This issue does not affect popular domains such as .co.uk, .co.in, or .com. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-0721 to this issue.
A frame injection spoofing vulnerability has been discovered in the Konqueror web browser. This issue could allow a malicious website to show arbitrary content in a named frame of a different browser window. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-0746 to this issue.
Secunia Research discovered a window injection spoofing vulnerability affecting the Konqueror web browser. This issue could allow a malicious website to show arbitrary content in a different browser window. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-1158 to this issue.
A bug was discovered in the way kioslave handles URL-encoded newline (%0a) characters before the FTP command. It is possible that a specially crafted URL could be used to execute any ftp command on a remote server, or potentially send unsolicited email. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-1165 to this issue.
All users of KDE are advised to upgrade to this updated packages, which contain backported patches to correct these issues.
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs
for directions on how to configure yum and apt-get.
