[KDE Security Advisory]: Kate backup file permission leak

KDE Security Advisory: Kate backup file permission leak
Original Release Date: 2005-07-18
URL: http://www.kde.org/info/security/advisory-20050718-1.txt

0. References
   CVE CAN-2005-1920
   https://bugs.kde.org/show_bug.cgi?id=103331

1. Systems affected:

    All maintained versions of Kate and Kwrite as shipped with
    KDE 3.2.x up to including 3.4.0. KDE 3.1.x and older and
    KDE 3.4.1 and newer are not affected.
   

2. Overview:

    Kate / Kwrite create a file backup before saving a modified
    file. These backup files are created with default permissions,
    even if the original file had more strict permissions set.
   

3. Impact:

    Depending on the system security settings, backup files
    might be readable by other users.  Kate / Kwrite are
    network transparent applications and therefore this
    vulnerability might not be restricted to local users.
   

4. Solution:

    Source code patches have been made available which fix these
    vulnerabilities. Contact your OS vendor / binary package provider
    for information about how to obtain updated binary packages.

    A patch for KDE 3.4.0 is available from
