4 | Subject: [PATCH] make .forceput inaccessible | ||
5 | |||
6 | Bug #701343, #701344, #701345 | ||
7 | |||
8 | More defensive programming. We don't want people to access .forecput | ||
9 | even though it is no longer sufficient to bypass SAFER. The exploit | ||
10 | in #701343 didn't work anyway because of earlier work to stop the error | ||
11 | handler being used, but nevertheless, prevent access to .forceput from | ||
12 | .setuserparams2. | ||

4 | Subject: [PATCH 1/2] PDF interpreter - Decode ToUnicode entries of the form | ||
5 | /Identity-H/V | ||
6 | |||
7 | Bug #701003 "Text searchability broken due to omission of /ToUnicode /Identity-H" | ||
8 | |||
9 | The PDF references from 1.2 too 2.0 all state that the value associated | ||
10 | with a ToUnicode key in a FontDescriptor must be a stream object. However | ||
11 | this file (and one case seen previously, bug 687351) have FontDescriptor | ||
12 | dictionaries where the value associated with a /ToUnicode key is a | ||
13 | name object, in both cases /Identity-H. | ||
14 | |||
15 | Although this is clearly not legal, Acrobat not only tolerates it, it | ||
16 | actually uses it for search/copy/paste (see bug 701003 for details). | ||
17 | Without the key Acrobat is unable to successfully search the output file. | ||
18 | |||
19 | We can't simply preserve the name object as a ToUnicode value; when | ||
20 | handling ToUnicode we actually decode the CMap and build a | ||
21 | GlyphNames2Unicode map (an internal representation of the G2U data | ||
22 | produced by the Microsoft PostScript printer driver). When writing the | ||
23 | output file we use that information to get a Unicode value for each | ||
24 | character we write, and build a new ToUnicode CMap using that. | ||
25 | |||
26 | This commit tackles the problem by pre-scanning for a name object and | ||
27 | then checking to see if its Identity-H or Identity-V (although we have | ||
28 | not seen an Identity-V, there seems no reason why it wouldn't be | ||
29 | equally valid). If we find either of these then we construct a | ||
30 | GlyphNames2Unicode table for all possible values (0 - 65535) and store | ||
31 | that with the font as normal. When we write the output file we only | ||
32 | write the required entries for the subset font, so we write a now | ||
33 | completely legal ToUnicode CMap, and Acrobat is equally happy with that | ||
34 | as the original name. | ||
35 | |||
36 | If the ToUnicode value isn't a name object, or isn't one of the | ||
37 | identities then we proceed as before. This means we will print a | ||
38 | warning for non conforming ToUnicode entries and ignore them. | ||

5 | |||
6 | Bug #701450 "Safer Mode Bypass by .forceput Exposure in .pdfexectoken" | ||
7 | |||
8 | By abusing the error handler it was possible to get the PDFDEBUG portion | ||
9 | of .pdfexectoken, which uses .forceput left readable. | ||
10 | |||
11 | Add an executeonly appropriately to make sure that clause isn't readable | ||
12 | no mstter what. | ||
13 | |||
14 | Review all the uses of .forceput searching for similar cases, add | ||
15 | executeonly as required to secure those. All cases in the PostScript | ||
16 | support files seem to be covered already. | ||
