Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Symlink Attack
    An attacker positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name. The endpoint file may be either output or input. If the file is output, the result is that the endpoint is modified, instead of a file at the intended location. Modifications to the endpoint file may include appending, overwriting, corrupting, changing permissions, or other modifications. In some variants of this attack the attacker may be able to control the change to a file while in other cases they cannot. The former is especially damaging since the attacker may be able to grant themselves increased privileges or insert false information, but the latter can also be damaging as it can expose sensitive information or corrupt or destroy vital system or application files. Alternatively, the endpoint file may serve as input to the targeted application. This can be used to feed malformed input into the target or to cause the target to process different information, possibly allowing the attacker to control the actions of the target or to cause the target to expose information to the attacker. Moreover, the actions taken on the endpoint file are undertaken with the permissions of the targeted user or application, which may exceed the permissions that the attacker would normally have.
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

  - Bug fixes * Make zoom_default key work properly with
    --geometry * Only create caption directory when actually

    <http://github.com/derf/feh/issues/42> * read directory
    contents sorted by filename instead of 'randomly' (as
    returned by readdir) by default. Thanks talisein!
    <https://github.com/derf/feh/pull/20> * Show certain
    warnings in the image window as well as on the
    commandline <http://github.com/derf/feh/issues/43> *
    Change a patch for NETWM fullscreen support to only
    apply to fullscreen windows. This fixes the moving
    windows bug in fluxbox (since fluxbox doesn't report its
    window border width).
    <http://github.com/derf/feh/issues/22>
    <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=570903
    > * Minor manpage fixes.
    <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=625683
    > * Fix --auto-zoom / --zoom max/fill documentation, the
    'Auto-Zoom' menu option is now always checked when these
    options are used * Set _NET_WM_NAME and
    _NET_WM_ICON_NAME properties
    <http://github.com/derf/feh/issues/44> * The
    zoom_default key now works fine with --scale-down
    <http://github.com/derf/feh/issues/41> * Fix access of
    uninitialized memory / malloc/realloc clash in continued
    theme definition handling. Having a theme line with just
    one option/value pair used to produce undefined
    behaviour * Fix segfault upon unloadable images when
    image-related format specifiers (e.g. %h) are used in
    --title * Fix Imlib2 caching bug in reload (only worked
    after the second try) * Show correct image dimensions in
    for cached thumbnails * Fix zooming when --scale-down is
    used * Make in/out zoom use equal zoom ratio

  - Behavior changes/compatability * --menu-style is now
    deprecated * The --menu-bg option has been deprecated.
    It will be removed along with --menu-style by the end of
    2012. <http://github.com/derf/feh/issues/27> * Since the
    manual is way better structured and more detailed than
    the --help output, it now simply refers to the manual. *
    The 'A' key (toggle_aliasing) now actually changes the
    current window, and not just the default for new windows
    * Show images in current directory when invoked without
    file arguments * The --bg options are now
    Xinerama-aware. That is, they set the image in the
    respective mode (scale/fill/max/center) on each Xinerama
    screen. Use --no-xinerama to disable this. * Add --zoom
    fill as equivalent for --auto-zoom * Remove builtin http
    client (--builtin) * http images are now viewed using
    libcurl, not wget (thanks to talisein) This adds libcurl
    as dependency, and removes the wget recommendation *
    Allow commandline options to override those set in a
    theme * Remove support for FEH_OPTIONS (was deprecated
    >5 years ago) * Restrict available modifiers to
    Control/Mod1/Mod4 * The themes are now read from
    ~/.config/feh/themes (BC for .fehrc exists) * Key
    bindings can now be configured via ~/.config/feh/keys *
    Removes --rcpath, use XDG_CONFIG_HOME instead * Increase
    movement steps for Ctrl+Left etc.

  - Features * You can now use the next/prev/jump keys to
    navigate thumbnails. Use the render key to open the
    currently selected thumbnail.
    <http://github.com/derf/feh/issues/26> * Option to
    disable antialiasing, either global (--force-aliasing)
    or per image (press 'A' to toggle, keybinding
    toggle_aliasing) * Use SIGUSR1/SIGUSR2 to reload all
    images in multiwindow mode * Add --zoom max (zooming
    like in --bg-max)

    descriptionThe remote host is affected by the vulnerability described in GLSA-201110-08 (feh: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in feh. Please review the CVE identifiers referenced below for details. Impact : A malicious entity might entice a user to visit a URL using the --wget-timestamp option, thus executing arbitrary commands via shell metacharacters; a malicious local user could perform a symlink attack and overwrite arbitrary files. Workaround : There is no known workaround at this time.
