Multiple vulnerabilities in Konqueror in KDE 3.3.1 and earlier (1) allow access to restricted Java classes via JavaScript and (2) do not properly restrict access to certain Java classes from the Java applet, which allows remote attackers to bypass sandbox restrictions and read or write arbitrary files.

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:065 advisory.

    The kdelibs packages include libraries for the K Desktop Environment.

    Two flaws were found in the sandbox environment used to run Java-applets in     the Konqueror web browser. If a user has Java enabled in Konqueror and     visits a malicious website, the website could run a carefully crafted     Java-applet and obtain escalated privileges allowing reading and writing of     arbitrary files with the privileges of the victim.  The Common     Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name     CAN-2004-1145 to this issue.

    A flaw was discovered in the FTP kioslave.  KDE applications such as     Konqueror could be forced to execute arbitrary FTP commands via a carefully     crafted ftp URL.  The URL could also be crafted in such a way as to send an     arbitrary email via SMTP.  An attacker could make use of this flaw if a     victim visits a malicious web site. The Common Vulnerabilities and     Exposures project has assigned the name CAN-2004-1165 to this issue.

    Users should update to these erratum packages which contain backported     patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-200501-16 (Konqueror: Java sandbox vulnerabilities)

    Konqueror contains two errors that allow JavaScript scripts and Java     applets to have access to restricted Java classes.
  Impact :

    A remote attacker could embed a malicious Java applet in a web page and     entice a victim to view it. This applet can then bypass security     restrictions and execute any command, or access any file with the     rights of the user running Konqueror.
  Workaround :

    There is no known workaround at this time.

A vulnerability in the Konqueror webbrowser was discovered where an untrusted java applet could escalate privileges (through JavaScript calling into Java code). This includes the reading and writing of files with the privileges of the user running the applet.

The provided packages have been patched to correct this problem.
