PLATFORM: Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS, ES, WS (v. 4) DAMAGE: 1) The Konqueror browser vulnerability allows remote attackers to spoof domain names using punycode encoded domain names; 2) The dcopserver has a denial-of-service vulnerability; and 3) The dcopidlng script vulnerability creates temporary files with predictable filenames which could allow local users to overwrite arbitrary files via a symlink attack. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is LOW. A local user may be able to elevate privileges ASSESSMENT: using a symlink attack. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/p-159.shtml ORIGINAL BULLETIN: Red Hat RHSA-2005:325-07 https://rhn.redhat.com/errata/RHSA-2005-325.html CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2005-0237 CAN-2005-0365 CAN-2005-0396 ______________________________________________________________________________ [***** Start Red Hat RHSA-2005:325-07 *****] Important: kdelibs security update Advisory: RHSA-2005:325-07 Type: Security Advisory Issued on: 2005-03-23 Last updated on: 2005-03-23 Affected Products: Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux WS (v. 4) CVEs (cve.mitre.org): CAN-2005-0237 CAN-2005-0365 CAN-2005-0396 Details Updated kdelibs packages that fix several security issues are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kdelibs package provides libraries for the K Desktop Environment. The International Domain Name (IDN) support in the Konqueror browser allowed remote attackers to spoof domain names using punycode encoded domain names. Such domain names are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0237 to this issue. Sebastian Krahmer discovered a flaw in dcopserver, the KDE Desktop Communication Protocol (DCOP) daemon. A local user could use this flaw to stall the DCOP authentication process, affecting any local desktop users and causing a reduction in their desktop functionality. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0396 to this issue. A flaw in the dcopidlng script was discovered. The dcopidlng script would create temporary files with predictable filenames which could allow local users to overwrite arbitrary files via a symlink attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0365 to this issue. Users of KDE should upgrade to these erratum packages which contain backported patches to correct these issues. Solution Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ Updated packages Red Hat Desktop (v. 4) -------------------------------------------------------------------------------- SRPMS: kdelibs-3.3.1-3.6.src.rpm 6ccf8717107ecc6d72b35704aaa9e07e IA-32: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-devel-3.3.1-3.6.i386.rpm 1af694976c9994ff3bc42b04ed122684 x86_64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.x86_64.rpm 1a99bb1ca25663786baca88582364276 kdelibs-devel-3.3.1-3.6.x86_64.rpm 918fbe7a0df8853c16213e9cc85311ca Red Hat Enterprise Linux AS (v. 4) -------------------------------------------------------------------------------- SRPMS: kdelibs-3.3.1-3.6.src.rpm 6ccf8717107ecc6d72b35704aaa9e07e IA-32: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-devel-3.3.1-3.6.i386.rpm 1af694976c9994ff3bc42b04ed122684 IA-64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.ia64.rpm aeac4b10cefa2eb651331da7d7543688 kdelibs-devel-3.3.1-3.6.ia64.rpm 86c14fcc2971949ae7d2bf6d4dc64ceb PPC: kdelibs-3.3.1-3.6.ppc.rpm d7b5bea6a04c878784dcbf7753cd0b41 kdelibs-3.3.1-3.6.ppc64.rpm b42f3377c51e8de4370f41daec826078 kdelibs-devel-3.3.1-3.6.ppc.rpm 63f50dac91194f9964f7c6cfad306be5 s390: kdelibs-3.3.1-3.6.s390.rpm 69622bbacd11c294bd01e98434a5b13b kdelibs-devel-3.3.1-3.6.s390.rpm e54406f8e75005d869539b701bddbe4f s390x: kdelibs-3.3.1-3.6.s390.rpm 69622bbacd11c294bd01e98434a5b13b kdelibs-3.3.1-3.6.s390x.rpm 6898fa8e5397b0c634a88f09872cd348 kdelibs-devel-3.3.1-3.6.s390x.rpm 65d18f1af50501dd67c477ea4e1fc3a5 x86_64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.x86_64.rpm 1a99bb1ca25663786baca88582364276 kdelibs-devel-3.3.1-3.6.x86_64.rpm 918fbe7a0df8853c16213e9cc85311ca Red Hat Enterprise Linux ES (v. 4) -------------------------------------------------------------------------------- SRPMS: kdelibs-3.3.1-3.6.src.rpm 6ccf8717107ecc6d72b35704aaa9e07e IA-32: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-devel-3.3.1-3.6.i386.rpm 1af694976c9994ff3bc42b04ed122684 IA-64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.ia64.rpm aeac4b10cefa2eb651331da7d7543688 kdelibs-devel-3.3.1-3.6.ia64.rpm 86c14fcc2971949ae7d2bf6d4dc64ceb x86_64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.x86_64.rpm 1a99bb1ca25663786baca88582364276 kdelibs-devel-3.3.1-3.6.x86_64.rpm 918fbe7a0df8853c16213e9cc85311ca Red Hat Enterprise Linux WS (v. 4) -------------------------------------------------------------------------------- SRPMS: kdelibs-3.3.1-3.6.src.rpm 6ccf8717107ecc6d72b35704aaa9e07e IA-32: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-devel-3.3.1-3.6.i386.rpm 1af694976c9994ff3bc42b04ed122684 IA-64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.ia64.rpm aeac4b10cefa2eb651331da7d7543688 kdelibs-devel-3.3.1-3.6.ia64.rpm 86c14fcc2971949ae7d2bf6d4dc64ceb x86_64: kdelibs-3.3.1-3.6.i386.rpm 105b9b5875503e735f0ee528b98b503b kdelibs-3.3.1-3.6.x86_64.rpm 1a99bb1ca25663786baca88582364276 kdelibs-devel-3.3.1-3.6.x86_64.rpm 918fbe7a0df8853c16213e9cc85311ca (The unlinked packages above are only available from the Red Hat Network) Bugs fixed (see bugzilla for more information) 147405 - CAN-2005-0237 homograph spoofing 148822 - CAN-2005-0365 dcopidlng insecure temporary file usage 150090 - CAN-2005-0396 kdelibs DCOP DoS References http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0237 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0365 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0396 http://www.kde.org/info/security/advisory-20050316-3.txt http://www.kde.org/info/security/advisory-20050316-2.txt http://www.kde.org/info/security/advisory-20050316-1.txt -------------------------------------------------------------------------------- These packages are GPG signed by Red Hat for security.
