CVE-2010-1748

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.
