[Core/CD] Prevent stack overflow when detecting OGG track silence
2026-10-06 16:34:39 +02:00

Bound the CD audio silence probe to one sample
...
The automatic OGG silence probe asked the decoder for 32 bytes of PCM
output into a 12-byte stack buffer. A valid audio track could therefore
overwrite 20 bytes of cdd_load's stack while a disc was mounted.
Only the first four-byte stereo sample is inspected. Limit both Vorbis
decoder calls to that size.

Bound ZIP extraction before narrowing its size
...
The SDL, GCW0, and PSP2 loaders converted the archive's unsigned
uncompressed size to int before comparing it with the ROM buffer limit.
Values above INT_MAX became negative and were passed to the unzip API as
a large unsigned length, allowing decompression past the ROM buffer.
Compare in the archive size type and narrow only after applying the
destination limit.

Validate restored VDP and PCM indexes
...
Save states can restore fifo_idx and pcm.index outside their backing
arrays. Canonicalize both values immediately after loading them so later
emulated hardware writes stay within the native arrays.

Bound CHD track metadata fields
...
cdd_load parses CHD metadata into 16-byte stack buffers. Limit each
string conversion to 15 bytes and terminate metadata at its returned
length so a malformed image cannot overwrite or overread the stack.
