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"
References
