Fabian Giesen 24fa1ff2e9 stb_image: Fix broken indenting introduced earlier 2023-01-22 19:44:49 -08:00
Fabian Giesen 0613e9c043 stb_image: Tweak end-of-JPEG junk scanning loop. 
Be a bit more picky about what we consider a valid marker.
0xff 0x00 (stuffed 0 byte) should not count.

Fixes issue #1409.

Fabian Giesen 1096389590 stb_image: Accept some extra data between BMP header and payload 
Limit to 1k, which is the maximum size of a 256-entry palette that
would ordinarily go there. It feels sensible to relax this a bit but
we don't want to go overboard.

Fixes issue #1325.

Fabian Giesen 51d295e33e stb_image: Add trailing semicolon to usage example 
Fixes issue #1330 reported by lunasorcery.

Fabian Giesen 038b6ab9ec stb_image: Avoid stdint.h on 32-bit Symbian. 
As suggested by "mupfdev" on Github. We don't have a way to test
here but seems simple enough.

Fixes issue #1321.

Neil Bickford 9f22cc9008 stb_image PNG: Checks for invalid DEFLATE codes. 
Specifically, this rejects length codes 286 and 287, and distance codes 30 and 31.
This avoids a scenario in which a file could contain a table in which
0 corresponded to length code 287, which would result in writing 0 bits.

Neil Bickford 47164e4086 Add checks for signed integer overflow; further guard against cases where stbi__grow_buffer_unsafe doesn't read all bits required. 2022-11-29 00:36:36 -08:00

Neil Bickford 84b94010a7 Add checks for PNM integer read overflows, add a 1GB limit on IDAT chunk sizes to fix an OOM issue, and check for a situation where a sequence of bad Huffman code reads could result in a left shift by a negative number. 2022-11-29 00:36:36 -08:00
Neil Bickford 2a02ff76b5 Fixes two stb_image issues that could occur with specially constructed HDR and PGM files.

Fabian Giesen 5ba0baaa26 stb_image: Reject fractional JPEG component subsampling ratios 
The component resamplers are not written to support this and I've
never seen it happen in a real (non-crafted) JPEG file so I'm
fine rejecting this as outright corrupt.

Fixes issue #1178.
