GHSA-2CGV-28VR-RV6J libcrux incorrectly calculates on aarch64

On platforms without the core::arch::aarch64::vxarqu64 intrinsic, an unverified fallback in libcrux-intrinsics v0.0.3 passed incorrect arguments and produced wrong results. This corrupted SHA-3 digests and caused libcrux-ml-kem and libcrux-ml-dsa to sample incorrectly, yielding incorrect shared...

Important: php

Issue Overview: In PHP versions prior to 7.4.33, 8.0.25 and 8.2.12, when using imageloadfont function in gd extension, it is possible to supply a specially crafted font file, such as if the loaded font is used with imagechar function, the read outside allocated buffer will be used. This can lead ...

XKCP: buffer overflow in the SHA-3 reference implementation

A flaw was found in the Keccak XKCP SHA-3 reference implementation. The sponge function interface allows partial input data to be processed, and partial output to be produced. When at least one of these has a length of 4294967096 bytes or more, it can result in elimination of cryptographic...
