TLS certificate common name validation bypass

The NATS official Rust clients are vulnerable to MitM when using TLS. The common name of the server's TLS certificate is validated against the hostname provided by the server's plaintext INFO message during the initial connection setup phase. A MitM proxy can tamper with the host field's value by...

`openssl` `X509NameBuilder::build` returned object is not thread safe

OpenSSL has a modified bit that it can set on on X509NAME objects. If this bit is set then the object is not thread-safe even when it appears the code is not modifying the value. Thanks to David Benjamin Google for reporting this issue...

Miscompilation in cortex-m-rt 0.7.1 and 0.7.2

Version 0.7.1 of the cortex-m-rt crate introduced a regression causing the stack to NOT be eight-byte aligned prior to calling main or any other specified entrypoint, violating the stack ABI of AAPCS32, the default ABI used by all Cortex-M targets. This regression is also present in version 0.7.2...

`NULL` dereference validating DSA public key

An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVPPKEYpubliccheck function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted sources which could allo...

Double free after calling `PEM_read_bio_ex`

The function PEMreadbioex reads a PEM file from a BIO and parses and decodes the "name" e.g. "CERTIFICATE", any header data and the payload data. If the function succeeds then the "nameout", "header" and "data" arguments are populated with pointers to buffers containing the relevant decoded data...

Use-after-free following `BIO_new_NDEF`

Force cast a &Vec<T> to &[T]

In function Table::asref, a reference of vector is force cast to slice. There are multiple problems here: 1. To guarantee the size is correct, we have to first do Vec::shrinktofit. The function requires a mutable reference, so we have to force cast from immutable to mutable, which is UB. 2. Even ...

Improper validation of Windows paths could lead to directory traversal attack

Path resolution in hyper-staticfile didn't correctly validate Windows paths meaning paths like /foo/bar/c:/windows/web/screen/img101.png would be allowed and respond with the contents of c:/windows/web/screen/img101.png. Thus users could potentially read files anywhere on the filesystem. This onl...

out-of-bounds read possible when setting list-of-pointers

If a message consumer expects data of type "list of pointers", and if the consumer performs certain specific actions on such data, then a message producer can cause the consumer to read out-of-bounds memory. This could trigger a process crash in the consumer, or in some cases could allow...

Unsound API in `secp256k1` allows use-after-free and invalid deallocation from safe code

Because of incorrect bounds on method Secp256k1::preallocatedgennew it was possible to cause use-after-free from safe consumer code.
