--- Begin Message ---Package: libgraphicsmagick-q16-3 Version: 1.3.30+hg15796-1~deb9u1 Severity: important Somewhere in between GraphicsMagick 1.3.28 and 1.3.30, there was an internal API change which introduced case sensitivity into magick formats. Command-line tools seem to work, as do perl API's, but low-level WriteImage() calls that assume on case-insensitivity are now broken. Test case program (which is just the first GraphicsMagick API demo program with a single line added to set image->magick to "gif"): bob@stretch64-build:~$ cat casetest.c #include <stdio.h> #include <stdlib.h> #include <string.h> #include <time.h> #include <sys/types.h> #include <magick/api.h> int main ( int argc, char **argv ) { Image *image = (Image *) NULL; char infile[MaxTextExtent], outfile[MaxTextExtent]; int arg = 1, exit_status = 0; ImageInfo *imageInfo; ExceptionInfo exception; InitializeMagick(NULL); imageInfo=CloneImageInfo(0); GetExceptionInfo(&exception); if (argc != 3) { (void) fprintf ( stderr, "Usage: %s infile outfile\n", argv[0] ); (void) fflush(stderr); exit_status = 1; goto program_exit; } (void) strncpy(infile, argv[arg], MaxTextExtent-1 ); arg++; (void) strncpy(outfile, argv[arg], MaxTextExtent-1 ); (void) strcpy(imageInfo->filename, infile); image = ReadImage(imageInfo, &exception); if (image == (Image *) NULL) { CatchException(&exception); exit_status = 1; goto program_exit; } (void) strcpy(image->magick, "gif"); (void) strcpy(image->filename, outfile); if (!WriteImage (imageInfo,image)) { CatchException(&image->exception); exit_status = 1; goto program_exit; } program_exit: if (image != (Image *) NULL) DestroyImage(image); if (imageInfo != (ImageInfo *) NULL) DestroyImageInfo(imageInfo); DestroyMagick(); return exit_status; } bob@stretch64-build:~$ dpkg-query -W libgraphicsmagick-q16-3 libgraphicsmagick-q16-3 1.3.25-8 bob@stretch64-build:~$ gcc -o casetest casetest.c -O `GraphicsMagick-config --cppflags --ldflags --libs` bob@stretch64-build:~$ identify x.png x.png PPM 800x600 800x600+0+0 8-bit sRGB 1.44MB 0.000u 0:00.000 bob@stretch64-build:~$ rm xxx bob@stretch64-build:~$ ls -l xxx ls: cannot access 'xxx': No such file or directory bob@stretch64-build:~$ ./casetest x.png xxx bob@stretch64-build:~$ ls -l xxx -rw-r--r-- 1 bob bob 7620 Oct 19 12:55 xxx bob@stretch64-build:~$ identify xxx xxx GIF 800x600 800x600+0+0 8-bit sRGB 128c 7.62KB 0.000u 0:00.000 bob@stretch64-build:~$ sudo apt-get install libgraphicsmagick-q16-3=1.3.30+hg15796-1~deb9u1 libgraphicsmagick1-dev=1.3.30+hg15796-1~deb9u1 Reading package lists...

TL;DR with 1.3.25 it generates a GIF image, and with 1.3.30 it reports that the 'gif' delegate is missing. I've also tested with 1.3.28 on bionic and it still works, so this is a >1.3.28 change. Needless to say, if someone has GraphicsMagick-based code which doesn't case convert formats to upper case to set the magick of an output file, upgrading to the 1.3.30 package will suddenly cause things to not work. This sort of incompatibility seems like a highly unfortunate thing to happen in what should be a stable security-based package update since it puts admins in the position of have to choose between security or applications continuing to work. -- System Information: Debian Release: 9.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-8-amd64 (SMP w/2 CPU cores) Locale: LANG=en_CA.ISO-8859-1, LC_CTYPE=en_CA.ISO-8859-1 (charmap=ISO-8859-1), LANGUAGE=en_CA:en (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libgraphicsmagick-q16-3 depends on: ii libbz2-1.0 1.0.6-8.1 ii libc6 2.24-11+deb9u3 ii libfreetype6 2.6.3-3.2 ii libgomp1 6.3.0-18+deb9u1 ii libice6 2:1.0.9-2 ii libjbig0 2.1-3.1+b2 ii libjpeg62-turbo 1:1.5.1-2 ii liblcms2-2 2.8-4+deb9u1 ii liblzma5 5.2.2-1.2+b1 ii libpng16-16 1.6.28-1 ii libsm6 2:1.2.2-1+b3 ii libtiff5 4.0.8-2+deb9u2 ii libwebp6 0.5.2-1 ii libwmf0.2-7 0.2.8.4-10.6 ii libx11-6 2:1.6.4-3 ii libxext6 2:1.3.3-1+b2 ii libxml2 2.9.4+dfsg1-2.2+deb9u2 ii zlib1g 1:1.2.8.dfsg-5 Versions of packages libgraphicsmagick-q16-3 recommends: ii ghostscript 9.20~dfsg-3.2+deb9u5 ii gsfonts 1:8.11+urwcyr1.0.7~pre44-4.3 Versions of packages libgraphicsmagick-q16-3 suggests: pn graphicsmagick-dbg <none> -- no debconf information
