Synopsis
=======
Adobe Acrobat Reader is vulnerable to a buffer overflow that could lead
to remote execution of arbitrary code.

Background
=========
Adobe Acrobat Reader is a utility used to view PDF files.

Affected packages
================
    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  app-text/acroread       < 5.10                            >= 5.10

Description
==========
A buffer overflow has been discovered in the email processing of Adobe
Acrobat Reader. This flaw exists in the mailListIsPdf function, which
checks if the input file is an email message containing a PDF file.

Impact
=====
A remote attacker could send the victim a specially-crafted email and
PDF attachment, which would trigger the buffer overflow and possibly
lead to the execution of arbitrary code with the permissions of the
user running Adobe Acrobat Reader.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Adobe Acrobat Reader users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/acroread-5.10"
