Description Michal Jaegermann 2003-01-06 05:11:03 UTC 
Description of problem:

http://www.idefense.com/advisory/12.23.02.txt describes how to attack
pdftops filter used, among other things, by CUPS.  That advisory is
specifically for a version of xpdf currently in rawhide but it mentions
that it applies to all earlier versions as well.  It also includes a
reference to a patch (although 'indexHighA != indexHighA && 0xff' test
would be likely marginally simpler).
Comment 1 Mark J. Cox 2003-01-08 11:12:12 UTC 
known issue, erratum for CUPS and Xpdf packages is in progress
Comment 2 Mark J. Cox 2003-02-10 08:33:05 UTC 
CUPS was released some time ago, xpdf updates were completed last week.
