    KDE Security Advisory: VCF file information reader vulnerability
    Original Release Date: 2004-01-14
    URL: http://www.kde.org/info/security/advisory-20040114-1.txt

    0. References

    1. Systems affected:

            All versions of kdepim as distributed with KDE versions 3.1.0
            through 3.1.4 inclusive.

    2. Overview:

            The KDE team has found a buffer overflow in the file
            information reader of VCF files.

            The Common Vulnerabilities and Exposures project (cve.mitre.org)
            has assigned the name CAN-2003-0988 to this issue.

    3. Impact:

            A carefully crafted .VCF file potentially enables local attackers
            to compromise the privacy of a victim's data or execute
            arbitrary commands with the victim's privileges.

            By default, file information reading is disabled for remote files.
            However, if previews are enabled for remote files, remote
            attackers may be able to compromise the victim's account.

    4. Solution:

            As a workaround, remove the kfile_vcf.desktop file.

            Users of KDE 3.1.x are advised to upgrade to KDE 3.1.5. A patch for
            KDE 3.1.4 is available for users who are unable to upgrade to
            KDE 3.1.5.

    5. Patch:

            A patch for KDE 3.1.4 is available from
            ftp://ftp.kde.org/pub/kde/security_patches :

            26469366cc393e50ff80d6dca8c74c58 post-3.1.4-kdepim-kfile-plugins.diff

    6. Time line and credits:

            15/12/2003 KDE developer Dirk Mueller discovers vulnerability.
            15/12/2003 Patches for the vulnerability are applied to CVS and
                       release preparations for KDE 3.1.5 are started.

            14/01/2004 Public advisory.
