Bumps image from 0.20.1 to 0.21.3. This update includes security fixes.

Vulnerabilities fixed

Sourced from The RustSec Advisory Database.

Flaw in interface may drop uninitialized instance of arbitrary types Affected versions of this crate would call Vec::set_len on an uninitialized vector with user-provided type parameter, in an interface of the HDR image format decoder. They would then also call other code that could panic before initializing all instances.

This could run Drop implementations on uninitialized types, equivalent to use-after-free, and allow an attacker arbitrary code execution.

Two different fixes were applied. It is possible to conserve the interface by ensuring proper initialization before calling Vec::set_len. Drop is no longer called in case of panic, though.

Starting from version 0.22, a breaking change to the interface requires callers to pre-allocate the output buffer and pass a mutable slice instead, avoiding all unsafe code.

Patched versions: >= 0.21.3 Unaffected versions: < 0.10.2

Changelog

Sourced from image's changelog.

Version 0.21.3

• Fixed an issue in HdrDecoder::read_image_transform that could drop uninitialized instances of arbitrary types on panic or expose uninitialized memory. The fix entails not dropping any value on error or panic, the method should only be used to read to types without Drop implementations.

Version 0.21.2

• Fixed a variety of crashes and opaque errors in webp
• Updated the png limits to be less restrictive
• Reworked even more unsafe operations into safe alternatives
• Derived Debug on FilterType and Deref on Pixel
• Removed a restriction on DXT to always require power of two dimensions
• Change the encoding of RGBA in bmp using bitfields
• Corrected various urls

Version 0.21.1

• A fairly important bugfix backport
• Fixed a potentially memory safety issue in the hdr and tiff decoders, see #885
• See the full advisory for an analysis
• Fixes ImageBuffer index calculation for very, very large images
• Fix some crashes while parsing specific incomplete pnm images
• Added comprehensive fuzzing for the pam image types

Version 0.21

• Updated README to use GenericImageView
• Removed outdated version number from CHANGES
• Compiles now with wasm-unknown-emscripten target
• Restructured ImageDecoder trait
• Updated README with a more colorful example for the Julia fractal
• Use Rust 1.24.1 as minimum supported version
• Support for loading GIF frames one at a time with animation::Frames
• The TGA decoder now recognizes 32 bpp as RGBA(8)
• Fixed to_bgra document comment
• Added release test script
• Removed unsafe code blocks several places
• Fixed overlay overflow bug issues with documented proofs

Version 0.20

• Clippy lint pass
• Updated num-rational dependency
• Added BGRA and BGR color types
• Improved performance of image resizing
• Improved PBM decoding
• PNM P4 decoding now returns bits instead of bytes
• Fixed move of overlapping buffers in BMP decoder
