2016-05-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - NEWS.txt: Updated with latest news.
> - magick/blob.c (OpenBlob): Remove support for reading input from a shell command, or writing output to a shell command, by prefixing the specified filename (containing the command) with a '|'. This feature provided a remote shell execution opportunity (CVE-2016-5118).

2016-05-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/url.c: Don't hide HTTP, FTP, and FILE URL support from '-list format' output. Ignore HTTP, FTP, and FILE as a useful file extension for determing the file format.

2016-05-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/render.c (ConvertPathToPolygon): Make sure that first edge is initialized. Make sure that points is not null.

2016-05-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/render.c (DrawImage): Fixed segmentation violation while reading file "275077586554139424.lqxdgqxtfs.svg" provided via private email from Gustavo Grieco on May 15, 2016. This is due to another CVE-2016-2317 related issue.

2016-05-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/svg.c ("C"): Fixed problems while reading files "aaphrbkwwe.svg.-1899680443073025602", "aaphrbkwwe.svg.-5751004588641220738", "aaphrbkwwe.svg.-8875730334406147537", and "aaphrbkwwe.svg.4495884156523242589" provided via private email from Gustavo Grieco on February 8, 2016.

2016-05-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/dib.c (ReadDIBImage): Verify that DIB file data is sufficient to meet claims made by file header. Validate image planes. Fixes Fixes problem reported by Hanno Böck on May 8th, 2016 via private email entitled "malloc issue in ReadDIBImage".

2016-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/msl.c (RegisterMSLImage): Ignore the file extension on MSL files. The only way to read an image from a MSL file (as opposed to explicitly running a MSL script with 'conjure') is by reading using a filename specification like "msl:filename". This is done for security reasons.
> - magick/render.c (DrawPrimitive): Fix Coverity issue 126378 "Resource leak".
> - coders/mat.c (DecompressBlock): Fix Coverity issue 126379 "Resource leak".

> - coders/mat.c Typo fix - matrix has nothing to do with PostScript.

2016-05-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/mat.c (DecompressBlock): Don't hang on a corrupt deflate stream when reading matlab v6 file. Fixes problem reported by Hanno Böck on May 8, 2016 via private email entitled "hang of matlab input file".

2016-05-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/image.c (SetImageInfo): Undocumented "TMP" magick prefix no longer removes the argument file after it has been read. This functionality is only used to support the "show" delegate which is used by options in the 'display' program which need to display a generated image in a new instance of 'display'. The "show" delegate is used by writing a temporary file to be viewed, and which should be removed before the program quits. Since the "TMP" feature was originally implemented, GraphicsMagick added a temporary file management subsystem which assures that temporary files are removed so this feature is not needed.
> - coders/tiff.c (ReadTIFFImage): Fix heap overflow with file "gkkxrilssm.tiff.-4678010562506843336" provided by Gustavo Grieco on February 8, 2006 via private email.
> - coders/viff.c (ReadVIFFImage): Fix problem with a very large malloc in sample file provided by Hanno Böck on May 7, 2016 with subject "large malloc in ReadVIFFImage".
> - coders/mvg.c (RegisterMVGImage): Do not auto-detect MVG format based on file extension. MVG files can then only be read by adding a "MVG:" prefix to the file name. There is already no auto-detection of MVG based on content.

2016-05-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/xpm.c (ReadXPMImage): Limit the number of XPM colors and assure array initialization. Fixes bad behavior with a sample file provided by Hanno Böck on May 6, 2016 with subject "Invalid free in ReadXPMImage".
> - coders/pcx.c (ReadPCXImage): Limit the number of PCX image planes allowed. Fixes an unreasonable memory allocation in a sample file provided by Hanno Böck on May 5, 2016.

2016-05-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - config/delegates.mgk.in: Gnuplot files are inherently insecure. Remove delegates support for reading them. Reported by John Lightsey via private email. Added -dSAFER to Ghostscript invokations in delegates.mgk for more secure execution. Reported by David Chan via SourceForge bug "#386 ghostscript delegates should explicitly use -dSAFER.".
> - magick/constitute.c (ReadImages): Avoid possible infinite ReadImage() recursion.

> - magick/render.c (DrawPolygonPrimitive): Fix divide by zero exception encountered while reading file "sigfpe.svg" posted by Gustavo Grieco on May 1, 2016 to the oss-security mailing list with subject "CVE request: DoS in multiple versions of GraphicsMagick".

Resolves problem observed while reading file "circular.svg" posted by Gustavo Grieco on May 1, 2016 to the oss-security mailing list with subject "CVE request: DoS in multiple versions of GraphicsMagick".

2016-04-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/render.c (DrawImage): Fix heap buffer overflow when reading aaphrbkwwe.svg.-1114777018469422437 from CVE-2016-2317 test cases. This resolves CVE-2016-2317 completely.

2016-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/msl.c (ProcessMSLScript): Need to close I/O blob before returning.
> - coders/psd.c (ReadPSDImage): Assure that allocated image is not dereferenced before checking if it is NULL. Check some memory calculations for overflow. (ReadPSDImage): Need to close I/O blob before returning.
> - coders/dib.c (ReadDIBImage): Use DestroyBlob() rather than DestroyBlobInfo().
> - coders/bmp.c (ReadBMPImage): Use DestroyBlob() rather than DestroyBlobInfo().
> - magick/blob.c: Improve blob tracing.
