Synopsis
========
Qpopper contains two vulnerabilities allowing an attacker to overwrite
arbitrary files and create files with insecure permissions.
Background
==========
Qpopper is a widely used server for the POP3 protocol.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-mail/qpopper < 4.0.5-r3 >= 4.0.5-r3
Description
===========
Jens Steube discovered that Qpopper doesn't drop privileges to process
local files from normal users (CAN-2005-1151). The upstream developers
discovered that Qpopper can be forced to create group or world
writeable files (CAN-2005-1152).
Impact
======
A malicious local attacker could exploit Qpopper to overwrite arbitrary
files as root or create new files which are group or world writeable.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Qpopper users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/qpopper-4.0.5-r3"
