Synopsis
========
A buffer overflow vulnerability has been discovered in
libcdio.
Background
==========
libcdio is a library for accessing CD-ROM and CD images.
Affected packages
=================
------------------------------------------------------------
-------
Package / Vulnerable /
Unaffected
------------------------------------------------------------
-------
1 dev-libs/libcdio < 0.78.2-r4
>= 0.78.2-r4
Description
===========
Devon Miller reported a boundary error in the
"print_iso9660_recurse()"
function in files cd-info.c and iso-info.c when processing
long
filenames within Joliet images.
Impact
======
A remote attacker could entice a user to open a specially
crafted ISO
image in the cd-info and iso-info applications, resulting in
the
execution of arbitrary code with the privileges of the user
running the
application. Applications linking against shared libraries
of libcdio
are not affected.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All libcdio users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=dev-libs/libcdio-0.78.2-r4"
