Synopsis
=======
libwmf is vulnerable to an integer overflow potentially resulting in
the execution of arbitrary code.

Background
=========
libwmf is a library for reading and converting vector images in
Microsoft's native Windows Metafile Format (WMF).

Affected packages
================
    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  media-libs/libwmf      < 0.2.8.4                       >= 0.2.8.4

Description
==========
infamous41md discovered that libwmf fails to do proper bounds checking
on the MaxRecordSize variable in the WMF file header. This could lead
to an head-based buffer overflow.

Impact
=====
By enticing a user to open a specially crafted WMF file, a remote
attacker could cause a heap-based buffer overflow and execute arbitrary
code with the permissions of the user running the application that uses
libwmf.

Workaround
=========
There is no known workaround for this issue.

Resolution
=========
All libwmf users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4"
