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 lt; 4.0.5-r3 gt;= 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 "gt;=net-mail/qpopper-4.0.5-r3"
