Title: wxGTK: User-assisted execution of arbitrary code
Date: September 02, 2010
Bugs: #277722
ID: 201009-01
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
An integer overflow vulnerability in wxGTK might enable remote
attackers to cause the execution of arbitrary code.
Background
==========
wxGTK is the GTK+ version of wxWidgets, a cross-platform C++ GUI
toolkit.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-libs/wxGTK < 2.8.10.1-r1 *>= 2.6.4.0-r5
>= 2.8.10.1-r1
Description
===========
wxGTK is prone to an integer overflow error in the wxImage::Create()
function in src/common/image.cpp, possibly leading to a heap-based
buffer overflow.
Impact
======
A remote attacker might entice a user to open a specially crafted JPEG
file using a program that uses wxGTK, possibly resulting in the remote
execution of arbitrary code with the privileges of the user running the
application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All wxGTK 2.6 users should upgrade to an updated version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/wxGTK-2.6.4.0-r5"
All wxGTK 2.8 users should upgrade to an updated version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/wxGTK-2.8.10.1-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since August 9, 2009. It is likely that your system is
already no longer affected by this issue.

Title: Maildrop: privilege escalation
Date: September 06, 2010
Bugs: #308043
ID: 201009-02
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Insecure permission handling in maildrop might allow local attackers to
elevate their privileges.
Background
==========
maildrop is the mail filter/mail delivery agent that is used by the
Courier Mail Server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-filter/maildrop < 2.4.2 >= 2.4.2
Description
===========
Christoph Anton Mitterer reported that maildrop does not properly drop
its privileges when run as root.
Impact
======
A local attacker could create a specially crafted .mailfilter file,
possibly leading to the execution of arbitrary commands with the "root"
group privileges. NOTE: Successful exploitation requires that maildrop
is run as root with the -d option.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All maildrop users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-filter/maildrop-2.4.2"
