Synopsis
========

A vulnerability in libsoup might allow remote attackers to execute
arbitrary code.

Background
==========

libsoup is an HTTP client/server library for GNOME.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-libs/libsoup < 2.56.1 >= 2.56.1

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

A stack based buffer overflow vulnerability was discovered in libsoup.

Impact
======

A remote attacker, by using specially crafted HTTP requests, could
execute arbitrary code with the privileges of the process.

Workaround

Synopsis
========

Multiple vulnerabilities have been found in LibTIFF, the worst of which
could result in the execution of arbitrary code.

Background
==========

The TIFF library contains encoding and decoding routines for the Tag
Image File Format. It is called by numerous programs, including GNOME
and KDE applications, to interpret TIFF images.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/tiff < 4.0.8 >= 4.0.8

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

Multiple vulnerabilities have been discovered in LibTIFF. Please review
the referenced CVE identifiers for details.

Impact
======

A remote attacker, by enticing the user to process a specially crafted
TIFF file, could possibly execute arbitrary code with the privileges of
the process, cause a Denial of Service condition, obtain sensitive
information, or have other unspecified impacts.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All LibTIFF users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-4.0.8"

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