Description

The cgi_initialize_string function in cgi-bin/var.c in the web interface in CUPS before 1.4.4 as used on Apple Mac OS X 10.5.8 Mac OS X 10.6 before 10.6.4 and other platforms does not properly handle parameter values containing a (percent) character without two subsequent hex characters which allows context-dependent attackers to obtain sensitive information from cupsd process memory via a crafted request as demonstrated by the (1) /admin?OP=redirect&URL= and (2) /admin?URL=/admin/&OP= URIs.
