Date:	04/02/2019
Bugs:	#641842
ID:	201904-05

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	Architecture(s)
app-backup/burp	< 2.1.32-r1	>= 2.1.32-r1	All supported architectures

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"
