Synopsis
========

A vulnerability was discovered in Gentoo's ebuild for BURP which could
lead to root privilege escalation.

Background
==========

A network backup and restore program.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-backup/burp            < 2.1.32-r1              >= 2.1.32-r1 

Description
===========

It was discovered that Gentoo’s BURP ebuild does not properly set
permissions or place the pid file in a safe directory. Additionally,
the first set of patches did not completely address this.  As such, a
revision has been made available that addresses all concerns of the
initial report.

Impact
======

A local attacker could escalate privileges.

Workaround
==========

Users should ensure the proper permissions are set as discussed in the
referenced bugs.

Resolution
==========

All BURP users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-backup/burp-2.1.32-r1"

References
