libcdio: User-assisted execution of arbitrary code


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200801-08 / libcdio
Release Date January 20, 2008
Latest Revision January 20, 2008: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
dev-libs/libcdio < 0.78.2-r4 >= 0.78.2-r4 All supported architectures

Related bugreports: #203777


A buffer overflow vulnerability has been discovered in libcdio.

2.  Impact Information


libcdio is a library for accessing CD-ROM and CD images.


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.


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.

3.  Resolution Information


There is no known workaround at this time.


All libcdio users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libcdio-0.78.2-r4"
