CVE-2020-35903

CVE-2020-35903 affects the Rust dync crate prior to 0.5.0, where VecCopy can misalign elements because Vec may store non-u8 types. This enables misaligned access when reading/writing elements of different types. The issue is documented across multiple sources (e.g., RustSec/RUSTSEC-2020-0050 and ...

kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned.

A buffer over-read flaw was found in cryptoauthencextractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash...

VecCopy allows misaligned access to elements

VecCopy::data is created as a Vec of u8 but can be used to store and retrieve elements of different types leading to misaligned access. The issue was resolved in v0.5.0 by replacing data being stored by Vec with a custom managed pointer. Elements are now stored and retrieved using types with prop...
