Date: November 07, 2004
Bugs: #68846, #69147
ID: 200411-13:01

Synopsis
=======
dispatch-conf (included in Portage) and qpkg (included in Gentoolkit) are vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files with the rights of the user running the script.
Background
=========
Portage is Gentoo's package management tool. The dispatch-conf utility allows for easy rollback of configuration file changes and automatic updates of configurations files never modified by users. Gentoolkit is a collection of Gentoo specific administration scripts, one of which is the portage querying tool qpkg.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/portage = 2.0.51-r3
2 app-portage/gentoolkit = 0.2.0_pre10-r1
*>= 0.2.0_pre8-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
==========
dispatch-conf and qpkg use predictable filenames for temporary files.
Impact
=====
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When an affected script is called, this would result in the file to be overwritten with the rights of the user running the dispatch-conf or qpkg, which could be the root user.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All Portage users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/portage-2.0.51-r3"
All Gentoolkit users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-portage/gentoolkit-0.2.0_pre8-r1"
Availability
===========
