This is not required by the TIFF standards. - -We than read the transfer function for every page. Depending on the -transfer function, we allocate either 2 or 4 bytes to the XREF buffer. -We allocate this memory after we read in the transfer function for the -page. - -For the first exploit - POC1, this file has 3 pages. For the first page -we allocate 2 extra extra XREF entries. Then for the next page 2 more -entries. Then for the last page the transfer function changes and we -allocate 4 more entries. - -When we read the file into memory, we assume we have 4 bytes extra for -each and every page (as per the last transfer function we read). Which -is not correct, we only have 2 bytes extra for the first 2 pages. As a -result, we end up writing past the end of the buffer. - -There are also some related issues that this also fixes. For example, -TIFFGetField can return uninitalized pointer values, and the logic to -detect a N=3 vs N=1 transfer function seemed rather strange. - -It is also strange that we declare the transfer functions to be of type -float, when the standard says they are unsigned 16 bit values. This is -fixed in another patch. - -This patch will check to ensure that the N value for every transfer -function is the same for every page. If this changes, we abort with an -error. In theory, we should perhaps check that the transfer function -itself is identical for every page, however we don't do that due to the -confusion of the type of the data in the transfer function. ---- - libtiff/tif_dir.c | 3 +++ - tools/tiff2pdf.c | 69 +++++++++++++++++++++++++++++++---------------- - 2 files changed, 49 insertions(+), 23 deletions(-) - -diff --git a/libtiff/tif_dir.c b/libtiff/tif_dir.c -index f00f808..c36a5f3 100644 ---- a/libtiff/tif_dir.c -+++ b/libtiff/tif_dir.c -@@ -1067,6 +1067,9 @@ _TIFFVGetField(TIFF* tif, uint32 tag, va_list ap) - if (td->td_samplesperpixel - td->td_extrasamples > 1) { - *va_arg(ap, uint16**) = td->td_transferfunction[1]; - *va_arg(ap, uint16**) = td->td_transferfunction[2]; -+ } else { -+ *va_arg(ap, uint16**) = NULL; -+ *va_arg(ap, uint16**) = NULL; - } - break; - case TIFFTAG_REFERENCEBLACKWHITE: -diff --git a/tools/tiff2pdf.c b/tools/tiff2pdf.c -index bdb9126..bd23c9e 100644 ---- a/tools/tiff2pdf.c -+++ b/tools/tiff2pdf.c -@@ -239,7 +239,7 @@ typedef struct { - float tiff_whitechromaticities[2]; - float tiff_primarychromaticities[6]; - float tiff_referenceblackwhite[2]; -- float* tiff_transferfunction[3]; -+ uint16* tiff_transferfunction[3]; - int pdf_image_interpolate; /* 0 (default) : do not interpolate, - 1 : interpolate */ - uint16 tiff_transferfunctioncount; -@@ -1049,6 +1049,8 @@ void t2p_read_tiff_init(T2P* t2p, TIFF* input){ - uint16 pagen=0; - uint16 paged=0; - uint16 xuint16=0; -+ uint16 tiff_transferfunctioncount=0; -+ uint16* tiff_transferfunction[3]; - - directorycount=TIFFNumberOfDirectories(input); - if(directorycount > TIFF_DIR_MAX) { -@@ -1157,26 +1159,48 @@ void t2p_read_tiff_init(T2P* t2p, TIFF* input){ - } - #endif - if (TIFFGetField(input, TIFFTAG_TRANSFERFUNCTION, -- &(t2p->tiff_transferfunction[0]), -- &(t2p->tiff_transferfunction[1]), -- &(t2p->tiff_transferfunction[2]))) { -- if((t2p->tiff_transferfunction[1] != (float*) NULL) && -- (t2p->tiff_transferfunction[2] != (float*) NULL) && -- (t2p->tiff_transferfunction[1] != -- t2p->tiff_transferfunction[0])) { -- t2p->tiff_transferfunctioncount = 3; -- t2p->tiff_pages[i].page_extra += 4; -- t2p->pdf_xrefcount += 4; -- } else { -- t2p->tiff_transferfunctioncount = 1; -- t2p->tiff_pages[i].page_extra += 2; -- t2p->pdf_xrefcount += 2; -- } -- if(t2p->pdf_minorversion < 2) -- t2p->pdf_minorversion = 2; -+ &(tiff_transferfunction[0]), -+ &(tiff_transferfunction[1]), -+ &(tiff_transferfunction[2]))) { -+ -+ if((tiff_transferfunction[1] != (uint16*) NULL) && -+ (tiff_transferfunction[2] != (uint16*) NULL) -+ ) { -+ tiff_transferfunctioncount=3; -+ } else { -+ tiff_transferfunctioncount=1; -+ } - } else { -- t2p->tiff_transferfunctioncount=0; -+ tiff_transferfunctioncount=0; - } -+ -+ if (i > 0){ -+ if (tiff_transferfunctioncount != t2p->tiff_transferfunctioncount){ -+ TIFFError( -+ TIFF2PDF_MODULE, -+ "Different transfer function on page %d", -+ i); -+ t2p->t2p_error = T2P_ERR_ERROR; -+ return; -+ } -+ } -+ -+ t2p->tiff_transferfunctioncount = tiff_transferfunctioncount; -+ t2p->tiff_transferfunction[0] = tiff_transferfunction[0]; -+ t2p->tiff_transferfunction[1] = tiff_transferfunction[1]; -+ t2p->tiff_transferfunction[2] = tiff_transferfunction[2]; -+ if(tiff_transferfunctioncount == 3){ -+ t2p->tiff_pages[i].page_extra += 4; -+ t2p->pdf_xrefcount += 4; -+ if(t2p->pdf_minorversion < 2) -+ t2p->pdf_minorversion = 2; -+ } else if (tiff_transferfunctioncount == 1){ -+ t2p->tiff_pages[i].page_extra += 2; -+ t2p->pdf_xrefcount += 2; -+ if(t2p->pdf_minorversion < 2) -+ t2p->pdf_minorversion = 2; -+ } -+ - if( TIFFGetField( - input, - TIFFTAG_ICCPROFILE, -@@ -1837,10 +1861,9 @@ void t2p_read_tiff_data(T2P* t2p, TIFF* input){ - &(t2p->tiff_transferfunction[0]), - &(t2p->tiff_transferfunction[1]), - &(t2p->tiff_transferfunction[2]))) { -- if((t2p->tiff_transferfunction[1] != (float*) NULL) && -- (t2p->tiff_transferfunction[2] != (float*) NULL) && -- (t2p->tiff_transferfunction[1] != -- t2p->tiff_transferfunction[0])) { -+ if((t2p->tiff_transferfunction[1] != (uint16*) NULL) && -+ (t2p->tiff_transferfunction[2] != (uint16*) NULL) -+ ) { - t2p->tiff_transferfunctioncount=3; - } else { - t2p->tiff_transferfunctioncount=1; --- -2.17.0 - diff --git a/main/tiff/CVE-2018-10779.patch b/main/tiff/CVE-2018-10779.patch deleted file mode 100644 index 828d684708..0000000000 --- a/main/tiff/CVE-2018-10779.patch +++ /dev/null @@ -1,32 +0,0 @@ -From 981e43ecae83935625c86c9118c0778c942c7048 Mon Sep 17 00:00:00 2001 -From: Even Rouault <even.rouault@spatialys.com> -Date: Wed, 15 Aug 2018 16:34:40 +0200 -Subject: [PATCH] TIFFSetupStrips(): avoid potential uint32 overflow on 32-bit - systems with large number of strips.

This allows us to avoid expensive - checks in TIFFPrintDirectory. Also, it is quite possible that - an alternative photometric type would be developed (not part of the - standard) and would allow definition of Transfer Table.

This makes sure that in any case -where (b) would be respected but not (a), everything stays fine. - -(B) is fulfilled by the loop condition -'i < td->td_samplesperpixel - td->td_extrasamples'.
