Subject: [PATCH] Bug 697178: Add a file permissions callback
|
||||||
|
|
||||||
|
For the rare occasions when the graphics library directly opens a file
|
||||||
|
(currently for reading), this allows us to apply any restrictions on
|
||||||
|
file access normally applied in the interpteter.

Subject: [PATCH] DSC parser - validate parameters
|
||||||
|
|
||||||
|
Bug #697190 ".initialize_dsc_parser doesn't validate the parameter is a dict type before using it."
|
||||||
|
|
||||||
|
Regardless of any security implications, its simply wrong for a PostScript
|
||||||
|
operator not to validate its parameter(s).
|
||||||
|
|
||||||
|
No differences expected.
