Bugs: #70310

Synopsis
=======
mtink is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files with the rights of the user running the utility.
Background
=========
mtink is a status monitor and inkjet cartridge changer for some Epson printers.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/mtink < 1.0.5 >= 1.0.5
Description
==========
Tavis Ormandy from Gentoo Linux discovered that mtink uses insecure permissions on 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 mtink is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All mtink users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/mtink-1.0.5"
Availability
===========
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200411-17.xml
Concerns?
========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
