Severity: High
Title: Cyrus-SASL: Execution of arbitrary code
Date: July 12, 2009
Bugs: #270261
ID: 200907-09
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A buffer overflow in Cyrus-SASL might allow for the execution of
arbitrary code in applications or daemons that authenticate using SASL.
Background
==========
Cyrus-SASL is an implementation of the Simple Authentication and
Security Layer.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/cyrus-sasl < 2.1.23 >= 2.1.23
Description
===========
James Ralston reported that in certain situations, Cyrus-SASL does not
properly terminate strings which can result in buffer overflows when
performing Base64 encoding.
Impact
======
A remote unauthenticated user might send specially crafted packets to a
daemon using Cyrus-SASL, possibly resulting in the execution of
arbitrary code with the privileges of the user running the daemon or a
Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Cyrus-SASL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/cyrus-sasl-2.1.23"

Title: Syslog-ng: Chroot escape
Date: July 12, 2009
Bugs: #247278
ID: 200907-10
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Syslog-ng does not properly initialize its chroot jail allowing for an
escape if a separate vulnerability in Syslog-ng is exploited.
Background
==========
Syslog-ng is a flexible and scalable system logger.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/syslog-ng < 2.1.3 *>= 2.0.10
>= 2.1.3
Description
===========
Florian Grandel reported that Syslog-ng does not call chdir() before
chroot() which leads to an inherited file descriptor to the current
working directory.
Impact
======
A local attacker might exploit a separate vulnerability in Syslog-ng
and use this vulnerability to escape the chroot jail.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Syslog-ng 2.0 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-2.0.10"
All Syslog-ng 2.1 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-2.1.3"

Severity: Normal
Title: GStreamer plug-ins: User-assisted execution of arbitrary
code
Date: July 12, 2009
Bugs: #256096, #261594, #272972
ID: 200907-11
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Multiple vulnerabilities in multiple GStreamer plug-ins might allow for
the execution of arbitrary code.
Background
==========
The GStreamer plug-ins provide decoders to the GStreamer open source
media framework.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/gst-plugins-good < 0.10.14 >= 0.10.14
2 media-libs/gst-plugins-base < 0.10.22 >= 0.10.22
3 media-plugins/gst-plugins-libpng < 0.10.14-r1 >= 0.10.14-r1
-------------------------------------------------------------------
3 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Multiple vulnerabilities have been reported in several GStreamer
plug-ins:
* Tobias Klein reported two heap-based buffer overflows and an array
index error in the qtdemux_parse_samples() function in
gst-plugins-good when processing a QuickTime media .mov file
(CVE-2009-0386, CVE-2009-0387, CVE-2009-0397).
* Thomas Hoger of the Red Hat Security Response Team reported an
integer overflow that can lead to a heap-based buffer overflow in the
gst_vorbis_tag_add_coverart() function in gst-plugins-base when
processing COVERART tags (CVE-2009-0586).
* Tielei Wang of ICST-ERCIS, Peking University reported multiple
integer overflows leading to buffer overflows in gst-plugins-libpng
when processing a PNG file (CVE-2009-1932).
Impact
======
A remote attacker could entice a user or automated system using a
GStreamer plug-in to process a specially crafted file, resulting in the
execution of arbitrary code or a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All gst-plugins-good users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=media-libs/gst-plugins-good-0.10.14"
All gst-plugins-base users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=media-libs/gst-plugins-base-0.10.22"
All gst-plugins-libpng users should upgrade to the latest version:
# emerge --sync
# emerge -a -1 -v ">=media-plugins/gst-plugins-libpng-0.10.14-r1"
