BURP: Root privilege escalation — GLSA 201904-05

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

Affected Packages

app-backup/burp on all architectures
Affected versions < 2.1.32-r1
Unaffected versions >= 2.1.32-r1

Background

A network backup and restore program.

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"
