Title: FUSE: incorrect filtering of environment variables leading to
privilege escalation
Date: March 09, 2016
Bugs: #550152
ID: 201603-04
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
The fusermount binary in FUSE does not properly clear the environment
before invoking mount or umount as root that allows a local user to
overwrite arbitrary files.
Background
==========
FUSE provides an interface for filesystems implemented in userspace.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-fs/fuse < 2.9.4 >= 2.9.4
Description
===========
The fusermount binary calls setuid(geteuid()) to reset the RUID when it
invokes /bin/mount so that it can use privileged mount options that are
normally restricted if RUID != EUID. FUSE does not properly clear
environment variables before invoking mount or umount as root allowing
this to be passed to operations using elevated privileges such as
LIBMOUNT_MTAB that is used by the mount commands debugging feature.
Impact
======
The FUSE vulnerability allows a local, unprivileged user to overwrite
arbitrary files on the system.
Workaround
==========
There is no known work around at this time.
Resolution
==========
All FUSE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-fs/fuse-2.9.4"

Severity: Normal
Title: LibreOffice, OpenOffice: Multiple vulnerabilities
Date: March 09, 2016
Bugs: #521136, #522060, #528438, #534684, #547880, #547900, #565028
ID: 201603-05
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Multiple vulnerabilities have been found in both LibreOffice and
OpenOffice allowing remote attackers to execute arbitrary code or cause
Denial of Service.
Background
==========
Apache OpenOffice is the leading open-source office software suite for
word processing, spreadsheets, presentations, graphics, databases and
more.
LibreOffice is a powerful office suite; its clean interface and
powerful tools let you unleash your creativity and grow your
productivity.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/libreoffice < 4.4.2 >= 4.4.2
2 app-office/libreoffice-bin
< 4.4.2 >= 4.4.2
3 app-office/libreoffice-bin-debug
< 4.4.2 >= 4.4.2
4 app-office/openoffice-bin
< 4.1.2 >= 4.1.2
-------------------------------------------------------------------
4 affected packages
Description
===========
Multiple vulnerabilities were found in both LibreOffice and OpenOffice
that allow the remote execution of arbitrary code and potential Denial
of Service. These vulnerabilities may be exploited through multiple
vectors including crafted documents, link handling, printer setup in
ODF document types, DOC file formats, and Calc spreadsheets. Please
review the referenced CVE's for specific information regarding each.
Impact
======
A remote attacker could entice a user to open a specially crafted file
using the LibreOffice or OpenOffice suite of software. Execution of
these attacks could possibly result in the execution of arbitrary code
with the privileges of the process or a Denial of Service condition.
Workaround
==========
There is no known work around at this time.
Resolution
==========
All LibreOffice users should upgrade their respective packages to the
latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/libreoffice-4.4.2"
# emerge --ask --oneshot -v ">=app-office/libreoffice-bin-4.4.2"
# emerge -a --oneshot -v ">=app-office/libreoffice-bin-debug-4.4.2"
All OpenOffice users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=app-office/openoffice-bin-4.1.2"
