23
perform a safe multiply. A multiplication overflow results in
25
(MagickAllocateMemory): Check for size\_t value truncation/overflow
26
and zero size before deciding to allocate memory. Any detected
27
failure results in a NULL pointer being returned.

29
order to avoid C++ portability problem.

92
very sensitive to the size/range of the type used to pass and
93
store it, leading to increased possibility of error. There was

2007-07-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
614
- coders/xc.c (ReadXCImage): If ImageInfo type field is set to
615
TrueColorType or TrueColorMatteType type, then return a
616
DirectClass image, otherwise a PseudoClass image is returned as
617

642
(ReadFOOImage): Check for EOF while searching for start of image
645
- tests/Makefile.am: Don't test PTIF format with blob I/O since it
646
is not possible to pass the rwblob test and it is really an output
647
driver rather than a format.
649
- libtool: Update to latest CVS libtool.
651
- magick/constitute.c (ExportModulo8Quantum): Move Import and
652
Export macros from header file since they are not used anywhere
655
- coders/dpx.c: Add underscore suffix to macro local variable
656
names in order to avoid conflict with names in code using the
659
2007-07-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

671
from a controlled source (log.mgk), perform safe numeric
674
- coders/xwd.c (ReadXWDImage): Eliminate conflict between locally
675
defined OVERFLOW macro and similarly named macro under Windows.

692
patch sun\_segfault\_fix.
694
- magick/blob.c (ReadBlobStream): Never try to read data beyond
695
EOF in blob streams. Some (but not all) ReadBlob\*() methods
696
already implemented similiar checks. Moving it to the central
697
ReadBlobStream() increases robustness and prevents out-of-bounds
698
reads. From Debian readblob\_offset\_robustness patch.
700
- coders/pnm.c (ReadPNMImage): Validate pixel scaling. From
701
Debian pnm\_scale\_fix patch.

710
- magick/montage.c, PerlMagick/t/montage.t: Do not pass bogus
711
negative values to modulate shadow in montage. Instead, drop a
712
constant grey shadow like current ImageMagick. From Debian
713
montage\_shadow\_fix patch.
715
- coders/png.c (ReadMNGImage): MNG segfault fix. From Debian
716

Debian bmp\_overflow\_fix patch.
736
2007-07-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
738
- magick/utility.h (MagickReallocMemory): It seems that realloc()
739
frees the provided memory pointer if the requested size is zero.
740
This was causing MagickReallocMemory() to perform a double-free
741
under error conditions. Inspired by Debian
742
realloc\_double\_free\_fix patch by Daniel Kobras.
744
2007-07-18 Daniel Kobras <kobras@debian.org>

756
size\_t is an unsigned type.
758
2007-07-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
760
- magick/image.c (SetImageInfo): Address security issue noted by
762
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0082 in

may cause GraphicsMagick to crash.
766
- magick/utility.c (TranslateTextEx): New version of TranslateText
767
which allows copying each attribute via a user-provided callback
770
- magick/delegate.c (InvokeDelegate): Implement secure delegate
771
execution in POSIX environments in order to avoid injection of
772
arbitrary shell commands via carefully crafted filenames. Fixes
773
Debian Bug 345238 "[CVE-2005-4601] Shell command injection in
774
delegate code (via file names)"

807
don't use at all if the input is not seekable.
809
- coders/psd.c (ReadPSDImage): Eliminate memory leak when reading
810
PSD files. Fixes Sourceforge issue 1625477 "Memory leak reading
813
2007-06-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
815
- magick/command.c: Fixed -affine command argument

831
in order to obtain better read performance for 10-bit DPX.
833
- magick/blob.c (OpenBlob): Added support for MAGICK\_MMAP\_READ and
834
MAGICK\_MMAP\_WRITE environment variable options to enable input and
835
output file access using mmap().
837
2007-06-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
839
- magick/blob.c (OpenBlob): Use MAGICK\_IOBUF\_SIZE to tune the size
840
of the I/O buffer. Sometimes performance is improved by using

2007-06-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
850
- magick/blob.c (OpenBlob): Disable reading input files using
851
memory mapping since it has been learned that some operating
852
systems fail to do read-ahead on network files. Without
853
read-ahead, performance is poor.
855
- magick/resource.c (AcquireMagickResource): Map resource limit
856
was not being properly checked due to a typo. The memory limit
857
was being tested instead.
859
- coders/tiff.c (ReadTIFFImage): Use libtiff to decode OJPEG
860
compressed files into RGB. Probably requires new OJPEG
861
implementation from Joris Van Damme which is new in libtiff and
862
not yet released. I am not completely sure that this approach is
865
2007-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- coders/cineon.c (ReadCINEONImage): Alter sample scaling
877
- tests/rwblob.c, tests/rwfile.c: Allow some slop when testing
878
Cineon format with QuantumDepth=8 since we are currently only
879
supporting 10 bit samples.
881
2007-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
883
- coders/jpeg.c (ReadJPEGImage): Fix reading 12-bit grayscale
886
2007-05-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
888
- coders/cineon.c (WriteCINEONImage): Re-wrote Cineon writer from
889
scratch. There is no code originating from ImageMagick in this
890
source module any more.
892
2007-04-30 Fojtik Jaroslav <JaFojtik@seznam.cz>
894
- coders/art.c, coders.cut.c, coders/mat.c, coders/wpg.c: Add
895
support for PingImage() so that image identification is fast by
896
default. Also eliminates error message produced by mat.c due to
897
rotating an image which has no pixel cache.
899
2007-04-09 Fojtik Jaroslav <JaFojtik@seznam.cz>
901
- coders/wpg.c (ReadWPGImage): Fix for SourceForge bug id 1431805

is open. Fix for SourceForge bug id 1173713 "segfault in
910
- m4/acx\_pthread.m4 (ACX\_PTHREAD): Apply fixes necessary to
911
support C++ compiler properly.
913

915
- magick/GraphicsMagick.pc.in: Fix for SourceForge bug id 1576616
916
"Fix includedir variable in pkg-config files".
918
- magick/pixel\_cache.c (GetOnePixel): Fix for SourceForge bug id
919
1572357 "GetOnePixel definition appears incorrect". It is true
920
that this function is intended for read-only purposes and that the
921
PixelPacket value is returned directly.
923
- coders/pdf.c (WritePDFImage): Fix for SourceForge bug id 1510075
924
"Failed to write PDF with JPEG compression".
926
- magick/command.c (MogrifyImageCommand): Properly bubble up

944
2007-03-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
946
- coders/dpx.c (WriteDPXImage): Set DPX reference high quantity to
947
2.047 rather than 2.048 since zero is assumed to occupy one count
948
and 2.047 seems to be the convention even though the DPX
949
specification says the default is 2.048. Technicolor uses 2.047.
951
- m4/acx\_pthread.m4: Update version of ACX\_PTHREAD macro used.
