Upcoming

This project is in maintenance mode; no new features, just bug fixes. Unless I see fit or perhaps you would like to do so?

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)
security bugfixes: -fsanitize=address [2]

INTF:

- global buffer overflow: prevent buffer overflow when adding ':=\n' to key

ECAT6:

- stack buffer overflow: handle header strings as unsafe for MdcPrintStr()

DICOM:

- stack buffer overflow: MdcKillSpaces() for-loop within boundaries; added initial sanity checks

- 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: MdcGetImgBuffer() now checks for 0 bytes before calloc()

- heap buffer overflow: when pixeldata length is unexpected; exit dicom_single() without further processing

- WARNING: this release could break on older build environments; support for gtk+2 will most probably be dropped

(useful for single big dicom files > 4GB) [1]

- EXPERIMENTAL: largefile support for sizes > 4GB

- use off_t for file positions and Int64 for memory lengths

- resort to fseeko() and ftello() functions for largefile support

- NOTES:

triggered after receiving a big dicom set with related 32bit integer limitations (Aloma Blanch)
found and detailed by Zhenqing

port to Gtk4

Git source compiles for now. Reimplemented the Gtk+3 waiting dialog. Still missing: progress bars not working.
Yet a lot of work to be done reimplementing the same GUI stuff ... but now in accordance with Gtk4 peculiarities.
