2015-01-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/nt_base.c (Exit): Changed to return 'void'. Function can not return a value if it does not return.
> - magick/error.c (DefaultFatalErrorHandler): Invoke PanicDestroyMagick() rather than DestroyMagick(). If we are really that short on memory, DestroyMagick() might not work.
> - magick/magick.c (MagickPanicSignalHandler): Only use async-safe functions in signal handler. (PanicDestroyMagick): New function for emergency release of persistent resources just prior to program exit. Async-safe and does not acquire or release any heap memory.

2015-01-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/gif.c (WriteGIFImage): Don't use an unchecked value from GetImageAttribute(), even if the access succeeded before. Resolves Coverity CID 10219.
> - coders/dpx.c (StringToAttribute): Make sure that string is not accidentally shortened by one character if it occupies the full field size. (ReadDPXImage): Validate that the bits per sample claimed by the file header is a supported depth before using it further in the code. This might resolve Coverity CID 10071 "Bad shift operation". (ReadDPXImage): Check for EOF while reading forward to element data. Might solve Coverity CID 10305.
> - coders/dib.c (ReadDIBImage): Resolve Coverity CID 10228 "Integer overflowed argument". (ReadDIBImage): Hopefully resolve Coverity CID 10268 "Various", which is primarily about placing too much trust in the claimed number of colors.
> - coders/pnm.c (WritePNMImage): Fix overwrite of status by progress monitor. Remaining issues may lurk within. May resolve Coverity CID 10288.
> - coders/pdb.c: Resolve Coverity CID 11173 "Buffer not null terminated".

2015-01-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/magick.c (GetMagickInfoArray): Resolve Coverity CID 10212 "Missing unlock".

> - coders/png.c (ReadMNGImage): Fixed a cut-and-paste typo (change_delay should be change_timeout) reported by Coverity CID 10090.

2015-01-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c (CloneImage): The definition is poor as to what a non-orphan clone should do. However, the definition surely does not include crashing the software or supplanting the original image in an image list. Clone image blob and previous/next pointers but do not supplant original image in list. Resolves Coverity CID 10155.

2015-01-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/bit_stream.c (BitAndMasks): Avoid possible access one-beyond end of BitAndMasks array. It is not clear if there is a possible bug with 32-bit quantums. If there is a bug, it has not been noticed via testing. Resolves Coverity CID 10213.
> - magick/tempfile.c (AcquireTemporaryFileDescriptor): Avoid buffer overrun in the case of an astonishingly long environment variable string. Resolves Coverity CID 10267. (AddTemporaryFileToList): Use strlcpy() rather than strlcpy(). In practice, should not make a difference. Will quiet Coverity CID 10321.
> - magick/command.c (GMCommandSingle): Don't use the address of a stack allocation to update argv[0]. Removed updating argv[0] until a better design can be found. Resolves Coverity CID 10223. (GMCommandSingle): Plan B: Use static allocation from SetClientName() to both store the new command name and provide storage for argv[0].
> - magick/utility.c (SystemCommand): Fix possible overwrite of memory location due to uninitialized 'end' pointer. Resolves Coverity CID 10251.

> - coders/dpx.c (LSBPackedU32WordToOctets): Fix typo which adds severe corruption to encoded little-endian 32-bit packed output. The good news is that since the corruption is severe, it is easily visually detected. The problem has corrupted all such (little-endian 10-bit) output since it was originally implemented on 2007-06-17 (changeset 11686, first released in GraphicsMagick 1.1.8). GraphicsMagick preserves the endianness of input DPX files by default, defaults to big-endian, and DPX files are commonly big-endian, so this problem may not have occured for many usages. Problem was reported by Steve Dabner on the GraphicsMagick discussion mailing list.

> - magick/magick.c (MagickPanicSignalHandler): Print a message in the case of signals SIGXCPU and SIGXFSZ.
> - coders/bmp.c (ReadBMPImage): Don't hang in endless loop if EOF is encountered while checking for "BA" header.
> - coders/icon.c (ReadIconImage): Limit icon image allocation size.

2015-01-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/icon.c (ReadIconImage): Removed all of the previously-existing DIB reading code from icon.c and use new "ICODIB" reader to read DIB icons, or the PNG reader to read PNG icons.
> - coders/dib.c (ReadDIBImage): Added an "ICODIB" coder for internal use which reads a Windows BMP 3 DIB followed by a Windows ICO alpha mask. This allows existing DIB code to be used to read ICO directory entries.

> - coders/icon.c: The Windows ICO reader is now more robust. Still a work in progress since some files still can not be read or read incorrectly.

2015-01-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/resource.c (ListMagickResourceInfo): "kilo" for binary prefixes is supposed to be "Ki".
> - magick/utility.c (FormatSize): "kilo" for binary prefixes is supposed to be "Ki".

2015-01-01 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - coders/png.c: Use WidthResource and HeightResource instead of fixed 1-million limit for rows and columns.

2015-01-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/utility.c (FormatSize): Add 'i' to value range identifiers since these are all in units of 2^10 rather than 1000.
> - magick/pixel_cache.c (CheckImagePixelLimits): Fix typo and produce an informative error message.
> - magick/resource.c: Added support for Image width and height pixels resource limits.
> - magick/resource.h (ResourceType): New resource enumerations WidthResource and HeightResource.
> - magick/enum_strings.c (StringToResourceType): Added support for parsing '-limit Width' and '-limit Height'.
> - magick/pixel_cache.c (CheckImagePixelLimits): New function to test image to see if it exceeds pixels limits.
> - coders/viff.c (ReadVIFFImage): Make the VIFF reader robust with detecting and reporting problems.
