Unaligned read of `*const *const c_char` pointer

Affected versions dereference a potentially unaligned pointer. The pointer is commonly unaligned in practice, resulting in undefined behavior. In some build modes, this is observable as a panic followed by abort. In other build modes the UB may manifest in some other way, including the possibilit...

Double Public Key Signing Function Oracle Attack on `ed25519-dalek`

Versions of ed25519-dalek prior to v2.0 model private and public keys as separate types which can be assembled into a Keypair, and also provide APIs for serializing and deserializing 64-byte private/public keypairs. Such APIs and serializations are inherently unsafe as the public key is one of th...

`array!` macro is unsound in presence of traits that implement methods it calls internally

Affected versions of this crate called some methods using auto-ref. The affected code looked like this. rust let mut arr = $crate::core::mem::MaybeUninit::uninit; let mut vec = $crate::ArrayVec::::newarr.asmutptr as mut T; In this case, the problem is that asmutptr is a method of &mut MaybeUninit...

Fragile bounds check when sampling from image

A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered NaN cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected...

DNS rebinding vulnerability in rmcp Streamable HTTP server transport

Prior to version 1.4.0, the rmcp crate's Streamable HTTP server transport did not validate the incoming Host header. This allowed a malicious public website, via a DNS rebinding attack, to send requests to an MCP server running on the victim's loopback or private-network interface. An attacker wh...

Type confusion when accessing data from sublasses of subclasses of native types with `abi3` feature targeting Python 3.12 and up

PyO3 0.28.1 added support for pyclassextends=PyList struct NativeSub and other native types when targeting Python 3.12 and up with the abi3 feature. It was discovered that subclasses of such classes would use the type of the subclass when attempting to access to data of NativeSub contained within...
