-Subject: [PATCH] make .forceput inaccessible
-
-Bug #701343, #701344, #701345
-
-More defensive programming. We don't want people to access .forecput
-even though it is no longer sufficient to bypass SAFER. The exploit
-in #701343 didn't work anyway because of earlier work to stop the error
-handler being used, but nevertheless, prevent access to .forceput from
-.setuserparams2.

-Subject: [PATCH 1/2] PDF interpreter - Decode ToUnicode entries of the form
- /Identity-H/V
-
-Bug #701003 "Text searchability broken due to omission of /ToUnicode /Identity-H"
-
-The PDF references from 1.2 too 2.0 all state that the value associated
-with a ToUnicode key in a FontDescriptor must be a stream object. However
-this file (and one case seen previously, bug 687351) have FontDescriptor
-dictionaries where the value associated with a /ToUnicode key is a
-name object, in both cases /Identity-H.
-
-Although this is clearly not legal, Acrobat not only tolerates it, it
-actually uses it for search/copy/paste (see bug 701003 for details).
-Without the key Acrobat is unable to successfully search the output file.
-
-We can't simply preserve the name object as a ToUnicode value; when
-handling ToUnicode we actually decode the CMap and build a
-GlyphNames2Unicode map (an internal representation of the G2U data
-produced by the Microsoft PostScript printer driver). When writing the
-output file we use that information to get a Unicode value for each
-character we write, and build a new ToUnicode CMap using that.
-
-This commit tackles the problem by pre-scanning for a name object and
-then checking to see if its Identity-H or Identity-V (although we have
-not seen an Identity-V, there seems no reason why it wouldn't be
-equally valid). If we find either of these then we construct a
-GlyphNames2Unicode table for all possible values (0 - 65535) and store
-that with the font as normal. When we write the output file we only
-write the required entries for the subset font, so we write a now
-completely legal ToUnicode CMap, and Acrobat is equally happy with that
-as the original name.
-
-If the ToUnicode value isn't a name object, or isn't one of the
-identities then we proceed as before. This means we will print a
-warning for non conforming ToUnicode entries and ignore them.

-Subject: [PATCH 2/2] PDF interpreter - review .forceput security
-
-Bug #701450 "Safer Mode Bypass by .forceput Exposure in .pdfexectoken"
-
-By abusing the error handler it was possible to get the PDFDEBUG portion
-of .pdfexectoken, which uses .forceput left readable.
-
-Add an executeonly appropriately to make sure that clause isn't readable
-no mstter what.
-
-Review all the uses of .forceput searching for similar cases, add
-executeonly as required to secure those. All cases in the PostScript
-support files seem to be covered already.
-
-CVE: CVE-2019-14817
-Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git]
