Description of problem:
A buffer overrun in cd-info and libcdio was uncovered when one reads a
disk/image with a long joilet filename. Please see URL  and the Gentoo
bugreport  for more information and the patch (should be in upstream CVS now).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
mkdir -p tmp/dir1
mkisofs -J -R -volid My_Image -o test.iso tmp
iso-info -l test.iso
A fair number of applications link against libcdio (and also Livna ones). Please
do the update for all affected branches as soon as possible!
Actually, this is not that serious. The applications that use libcdio are not
vulnerable, as the problem lies in iso-info program only.
libcdio-0.78.2-4.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
