Maintenance release focused on decoder safety, the empty-viewer rendering path, and diagnostics coverage.
Security and robustness
- Targa colour-map decoding: out-of-bounds read on a crafted file. A pixel index below the map's first index passed through the bounds test rather than failing it — both fields are uint16_t, so the subtraction promoted to a negative int and wrapped to near SIZE_MAX, and for a difference of exactly −1 the offset arithmetic wrapped back to zero. A file declaring cmFirst = 1 with a pixel index of 0 was enough to reach a wild pointer. The index is now rejected before the subtraction.
- PNM header fields no longer overflow. Width, height and maximum-value parsing accumulated with v = v * 10 + d, which is undefined behaviour on a long run of digits and, in a release build, wrapped to values that passed the range checks below it. Parsing now saturates at INT_MAX, which every caller already treats as a rejection.
- PNM samples are clamped before scaling. The ASCII variants (P1/P2/P3) read samples without reference to maxVal, so a malformed file could hand the scaler a value that overflowed on its way to a byte. Samples outside the declared range are clamped.
Rendering
- The empty-viewer placeholder, the folder overlay and the window title are now driven from a single composition rather than three code paths that could disagree about what is on screen.
- Folder overlay text layout is built once and reused instead of being recomposed per frame.
- Placeholder rendering is consistent between the Direct2D and GDI back ends.
Diagnostics
- Slideshow start and stop are recorded in the general log.
- The network log now covers the beacon, the blacklist, client and server lifecycle, and TLS handshake outcomes — arrivals, departures and refusals name the peer address and port, so two connections from one host can be told apart.
- Logging remains off by default and costs a single atomic read per record point while it is off.
Fixes
- Playlist sort order is applied consistently when the order is changed from the menu.
Documentation
- The supported-format tables in the README and on the site now list every format the application actually decodes, including JPEG XR, DDS, camera RAW (DNG/CR2/CR3/NEF/ARW), Targa and APNG, along with the extension aliases each accepts.
- The shortcut reference has been corrected across the help panel, the README and the site. Every colour effect requires Ctrl — the plain presses of those keys are navigation. The previous tables listed the bindings as they were before that change.
- Added the missing entries for Ctrl+F3 (clear the VRAM cache), U (thumbnail strip visual effects), Ctrl+Shift+Enter (push this position to every connected instance), Right Shift as an alternative directory-panel toggle, Ctrl+O in the Server Log panel, and the -slideshowTransitionSource, -slideshowTransitionOrder and -slideshowTransitions command-line switches.
- Documented the Announce (beacon) item in the TCP/IP menu.
- Removed a stale entry claiming F12 cleared the thumbnail cache; that moved to Ctrl+F3 when F12 became the mirroring toggle.
Installation
Single portable executable, 9.8 MB. Windows 10 or newer, x64.
The C runtime is linked statically — no Visual C++ Redistributable is required. Nothing is installed and nothing is written outside the registry keys the application uses for its own settings.
