[GLSA]

Gentoo Linux Security Advisory

Title: libcdio: User-assisted execution of arbitrary code (GLSA 200801-08)
Severity: normal
Exploitable: remote
Date: January 20, 2008
Bug(s): #203777
ID: 200801-08

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: dev-libs/libcdio
Vulnerable: < 0.78.2-r4
Unaffected: >= 0.78.2-r4
Architectures: All supported architectures


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:
