Synopsis
========

A buffer overflow error in GMime might allow remote attackers to
execute arbitrary code or cause a Denial of Service condition.

Background
==========

GMime is a C/C++ library which may be used for the creation and parsing
of messages using the Multipurpose Internet Mail Extension (MIME).

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-libs/gmime               < 2.4.15                  >= 2.4.15
                                                           *>= 2.4.17
                                                           *>= 2.2.26

Description
===========

GMime contains a buffer overflow flaw in the GMIME_UUENCODE_LEN macro
in gmime/gmime-encodings.h.

Impact
======

A context-dependent attacker could possibly execute arbitrary code or
cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

GMime 2.4.x users on the PPC64 architecture should upgrade to the
latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/gmime-2.4.17"

GMime 2.4.x users on other architectures should upgrade to the latest
version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/gmime-2.4.15"

GMime 2.2.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/gmime-2.2.26"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
