Synopsis
========
lm_sensors is vulnerable to linking attacks, potentially allowing a
local user to overwrite arbitrary files.
Background
==========
lm_sensors is a software package that provides drivers for monitoring
the temperatures, voltages, and fans of Linux systems with hardware
monitoring devices.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/lm_sensors < 2.9.1-r1 >= 2.9.1-r1
Description
===========
Javier Fernandez-Sanguino Pena has discovered that lm_sensors
insecurely creates temporary files with predictable filenames when
saving configurations.
Impact
======
A local attacker could create symbolic links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When
the pwmconfig script of lm_sensors is executed, this would result in
the file being overwritten with the rights of the user running the
script, which typically is the root user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All lm_sensors users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/lm_sensors-2.9.1-r1"

Title: phpGroupWare: Multiple vulnerabilities
Date: August 30, 2005
Bugs: #102379
ID: 200508-20
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
phpGroupWare is vulnerable to multiple issues ranging from information
disclosure to a potential execution of arbitrary code.
Background
==========
phpGroupWare is a multi-user groupware suite written in PHP.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/phpgroupware < 0.9.16.008 >= 0.9.16.008
Description
===========
phpGroupWare improperly validates the "mid" parameter retrieved via a
forum post. The current version of phpGroupWare also adds several
safeguards to prevent XSS issues, and disables the use of a potentially
vulnerable XML-RPC library.
Impact
======
A remote attacker may leverage the XML-RPC vulnerability to execute
arbitrary PHP script code. He could also create a specially crafted
request that will reveal private posts.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All phpGroupWare users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/phpgroupware-0.9.16.008"
