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=E2=80=99s 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"
