in release 0.24.1 @ 24-Nov-2024 (Gtk+2 & Gtk+3)

  • option -cw (forced contrast remapping) now as intended for CT (= simply capping pixvalues between upper & lower value)
  • fix broken fallback format (i.e. to read DICOM without meta header)
  • PNG: fixed tiny memory leak due to unfreed comment buffer (-fsanitize=address)
  • ECAT6: replaced sprintf() string copies with strncpy() functions
  • security bugfixes / stability improvements: -fsanitize=address [1]
ALL:
- heap buffer overflow: MdcGetImgBuffer() now checks for 0 bytes before calloc()
INTF:
- global buffer overflow: prevent buffer overflow when adding ':=\n' to key
ECAT6:
- stack buffer overflow: handle header strings as unsafe for MdcPrintStr()
DICOM
- memory access violation: dicom_transfer() using a strncmp() safe global buffer
- null pointer dereference: mdc_dicom_printinfo() checks for NULL-pointer as values
- null pointer dereference: dicom_single() checks for proper e->value.CS before strncmp()
- heap buffer overflow: when pixeldata length is unexpected; exit dicom_single() without further processing
ACR+DICOM+INTF:
- stack buffer overflow: MdcKillSpaces() for-loop within boundaries; added initial sanity checks

in release 0.24.0 @ 24-May-2024 (Gtk+2 & Gtk+3)

DICOM

  • basic.c: quickfix for security vulnerability against malicious DICOM files (= buffer overflow) [1]
(as a workaround the supported element size is now limited to [UINT32_MAX - 4] bytes)

MSYS2

  • m-files.c: MdcGetLastPathDelim() correctly handles mixes of /forward/ & \backward\ slashes.
(bugfix improper filename creations within MSYS2 terminals)
  • dicom/log.c: fix similar compile error with gcc-14 related to system header <io.h> conflict: "ljpg/io.h" renamed to "inout.h".

Gtk+3

  • CSS Styling: small improvements in "speedometer" color scheme. Added our personal hundliv color scheme.


  1. Oops, our very first CVE-2024-29421 notified by Spike Reply Cyber Security Team


in release 0.23.0 @ 04-Jan-2023 (Gtk+2 & Gtk+3)

  • xmedcon.rb: pull in adwaita icons needed for some buttons (eg. increment / decrement).
  • m-fancy.c: printf 64bit integers as long long.
  • m-transf.c: reworked contrast remapping (BUGFIX?).
  • libmdc: got rid of needless GUI dependencies in core library (due to an evil source/Makefile.am),
    so it will be safe to combine AMIDE with XMedCon Gtk+3 and beyond.
  • xfilesel.c: set default name just before showing dialog; fixes name change when new file was loaded.


in release 0.22.0 @ 04-Mar-2022 (Gtk+2 & Gtk+3)

Gtk+3

  • no longer display an error dialog when cursor types are not found (flatpak)
  • environment variable XMEDCONCSS wasn't really read (appimage)

Gtk+2 & Gtk+3

  • configure: generate an installable m-depend.h with ax_prefix_config_h macro using LIBMDC_ prefix
  • stack slices: give stack warnings (differences) between consecutive images

in release 0.21.2 @ 20-Jul-2021 (Gtk+3)

  • Small addition in our speedometer CSS theme: window titlebar is now in dark mode too
  • Learned how to leave out annoying autotools reconfigure rules from Makefiles via AM_MAINTAINER_MODE macro
    • Why? working with most recent autotools version <> older autotools version on most systems <> users are not necessarily developers ...
  • Improvements for Wayland (CentOS Stream / OpenSUSE Tumbleweed)
    • Menu "Online info" core dumps due to "toplevel" window problem
    • Check "Gdk-CRITICAL gdk_monitor_get_workarea: assertion 'GDK_IS_MONITOR ()' failed"
    • gtk_window_set_transient_for(window, parent)
    • Not working GBC-widget (gamma, brightness, contrast)

in release 0.21.1 @ 01-May-2021 (Gtk+3)

  • Require libpng >= 1.6.0 for Ubuntu's sake
  • Added in GUI resizing to fifth and quint
  • Secured two sprintf() statements
  • Updated Inno Setup file for Gtk+3 dependencies
  • Fresh update of application icon
  • GIF89a: write "XMedCon" in application block

in release 0.21.0 @ 19-Feb-2021 (Gtk+3 - Fresh)

  • Now here it is. Finally a GUI port to Gtk+3 after plenty hours of searching & altering deprecated upon deprecated upon deprecated API functions while jumping over way too many hurdles on the way, featuring
    • personal theming with CSS (hello, dark mode)
    • change orientation of main menu
    • macOS: once again supported on brew
    • Windows: worked out how to get such simple Gtk+3 app running standalone with all Gtk+3 dependencies (but dropped 32-bit support on the way)

in release 0.17.0 @ 16-Feb-2021 (Gtk+2)

  • Our Gtk+2 compliant version. Quite some GUI changes by replacing deprecated functions; using cairo contexts, pango fonts, ...
  • Just an intermediary "sources only" release towards Gtk+3 compliance. Note @ 04-jan-2021: released RPM's too.

in release 0.16.3 @ 28-Nov-2020

  • Fix warnings from current gcc "-Wall" option.
  • NIFTI: Remove ".img" string from filenames instead of finding first dot with rude strchr('.') ... failing for '-o ./filename.ext' (1)
    (required because nifti1 library otherwise writes a separate two file .hdr & .img pair)
  • Mute deprecated warnings between Gtk+2 and Glib (>2.61.1) during compilation
    (-Wno-deprecated-declarations).
  • Fix currently broken extraction range handling.
  • GUI: on mswindows zoom window dialogs now display complete instead of partial.
  • GUI: set BILINEAR as default; HYPER seemed deprecated.
  1. issue discovered while solving a ticket by Sumiko Abe.

Initial Linux Flatpak based on release 0.16.2 @ 10-Aug-2020

  • After another long search proces, we finaly got our very first FlatPak ready for the latest release as a single download file instead of using yet another repository. (1)
  1. from advocacy by nokia808

Initial Linux AppImage based on release 0.16.2 @ 01-Aug-2020

  • After a long search proces, we finaly succeeded in creating a generic AppImage file for Linux. The AppImage documentation is rather troublesome and fragmented.

in release 0.16.2 @ 05-Aug-2019

  • must fflush(stdout) within MSYS2: no output on console when waiting for user input (-e, -i, -p, -r ...)
  • increased hardcoded number of loadable LUTs (= 999) because more LUTs are added in (X)MedCon-Extra.
  • BUGFIX: ECAT7 proper handling of patient_birth_date & scan_start_time (1)
  • removed broken #if(n)def HAVE_8BYTE_INT directives, allowing for int64_t and uint64_t pixel values.
  1. patch kindly offered by Jonathan Traum

xmedcon-extra-1.2.0 @ 27-Apr-2018

some tools in xmedcon-extra are updated due to slight changes in the library: now MdcInit() is mandatory for setting the host endianness.

in release 0.15.0 @ 11-Apr-2018

(just one minor bugfix; mostly fiddling with building the source code)
  • BUGFIX: output file generation fails with mixed path delimiters (mswindows/msys2). (1)
  • homebrew formula contributed for macOS package manager. (2)
  • architecture independent header files. (3)
  • routines added for checking endianess of host: just little or big; nothing else in between.
  • library has some minor changes as a result; so version number got bumped up.
  • modernizing configure and built, say C99 requirements; perhaps breaking older stuff...
