Synopsis
========
A vulnerability has been discovered in libcue which could allow for
arbitrary code execution.

Background
==========
libcue is a CUE Sheet Parser Library.

Affected packages
=================
Package Vulnerable Unaffected
----------------- ------------ ------------
media-libs/libcue < 2.2.1-r1 >= 2.2.1-r1

Description
===========
libcue does not check bounds in a loop and suffers from an integer
overflow flaw which can be exploited to take over the program.

Impact
======
Untrusted CUE sheet files can lead to arbitrary code execution.

app-misc/tracker-miners[cue] uses libcue to index CUE Sheet files in
directories. It is possible that downloading a malicious CUE Sheet file
into a directory indexed by tracker-miners could lead to remote code
execution.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All libcue users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libcue-2.2.1-r1"

References
