The kdenetwork packages contain a collection of networking applications for the K Desktop Environment. PLATFORM: Red Hat Desktop (v. 3) Red Hat Enterprise Linux AS, ES, WS (v. 2.1 and v.3) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor Debian GNU/Linux 3.0 (woody) SGI ProPack 3 Service Pack 4 for SGI Altix family of systems DAMAGE: A malicious local user could make use of this flaw to modify the /etc/hosts or /etc/resolv.conf files, which could be used to spoof domain information. SOLUTION: Apply the updated packages. ______________________________________________________________________________ VULNERABILITY The risk is LOW. A local user could modify system files such as ASSESSMENT: /etc/hosts or /etc/resolv.conf files. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/p-151.shtml ORIGINAL BULLETIN: https://rhn.redhat.com/errata/RHSA-2005-175.html ADDITIONAL LINKS: Debian Security Advisory DSA-692-1 http://www.debian.org/security/2005/dsa-692 SGI Security Advisory 20050302-01-U Security Update #30 http://www.sgi.com/support/security/advisories.html CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2005-0205 ______________________________________________________________________________ REVISION HISTORY: 03/08/2005 - revised to add a link to Debian Security Advisory DSA-692-1 for Debian GNU/Linux 3.0 (woody). 03/31/2005 - revised to add a link to SGI Security Advisory 20050302-01-U SGI Advanced Linux Environment 3 Security Update #30 for Patch 10151 for SGI ProPack 3 Service Pack 4. [***** Start Red Hat Security Advisory RHSA-2005:175-06 *****] Low: kdenetwork security update Advisory: RHSA-2005:175-06 Last updated on: 2005-03-03 Affected Products: Red Hat Desktop (v. 3) Red Hat Enterprise Linux AS (v. 2.1) Red Hat Enterprise Linux AS (v. 3) Red Hat Enterprise Linux ES (v. 2.1) Red Hat Enterprise Linux ES (v. 3) Red Hat Enterprise Linux WS (v. 2.1) Red Hat Enterprise Linux WS (v. 3) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor CVEs (cve.mitre.org): CAN-2005-0205 back Security Advisory Security Advisory Details: Updated kdenetwork packages that fix a file descriptor leak are now available. This update has been rated as having low security impact by the Red Hat Security Response Team The kdenetwork packages contain a collection of networking applications for the K Desktop Environment. A bug was found in the way kppp handles privileged file descriptors. A malicious local user could make use of this flaw to modify the /etc/hosts or /etc/resolv.conf files, which could be used to spoof domain information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0205 to this issue. Please note that the default installation of kppp on Red Hat Enterprise Linux uses consolehelper and is not vulnerable to this issue. However, the kppp FAQ provides instructions for removing consolehelper and running kppp suid root, which is a vulnerable configuration. Users of kdenetwork should upgrade to these updated packages, which contain a backported patch, and are not vulnerable to this issue.
