RUSTSEC-2023-0045 memoffset allows reading uninitialized memory

memoffset allows attempt of reading data from address 0 with arbitrary type. This behavior is an undefined behavior because address 0 to std::mem::sizeof may not have valid bit-pattern with T. Old implementation dereferences uninitialized memory obtained from std::mem::alignof. Older implementati...

RUSTSEC-2023-0044 `openssl` `X509VerifyParamRef::set_host` buffer over-read

When this function was passed an empty string, openssl would attempt to call strlen on it, reading arbitrary memory until it reached a NUL byte...

RUSTSEC-2023-0046 Misaligned pointer dereference in `ChunkId::new`

The function ChunkId::new creates a misaligned pointer by casting mutable pointer of u8 slice which has alignment 1 to the mutable pointer of u32 which has alignment 4, and dereference the misaligned pointer leading UB, which should not be allowed in safe function...

RUSTSEC-2023-0042 Ouroboros is Unsound

Summary Ouroboros has a soundness problem, but a fix has been implemented in 0.16.0. More details: In 0.15.0, Ouroboros works internally by creating a struct where all uses of 'this are replaced by 'static. However, a recent addition to Miri checks that references passed to functions are valid...

RUSTSEC-2023-0041 Remote Attackers can cause Denial-of-Service (packet loops) with crafted DNS packets

trust-dns and trust-dns-server are vulnerable to remotely triggered denial-of-service attacks, consuming both network and CPU resources. DNS messages with the QR=1 bit set are responded to with a FormErr response. This allows creating a traffic loop, in which these FormErr responses are sent...

RUSTSEC-2023-0038 Out-of-bounds array access leads to panic

Affected versions of the crate have several bugs where attacker-controlled input can result in the use of an out-of-bound array index. Rust detects the use of the out-of-bound index and causes the application to panic. An attacker may be able to use this to cause a denial-of-service. However, it ...

RUSTSEC-2023-0039 Out-of-bounds array access leads to panic

Affected versions of the crate have a bug where attacker-controlled input can result in the use of an out-of-bound array index. Rust detects the use of the out-of-bound index and causes the application to panic. An attacker may be able to use this to cause a denial-of-service. However, it is not...

RUSTSEC-2023-0125 Logs AWS credentials when TRACE-level logging is enabled

aws-sigv4 is a rust library for low level request signing in the aws cloud platform. The awssigv4::SigningParams struct had a derived Debug implementation. When debug-formatted, it would include a user's AWS access key, AWS secret key, and security token in plaintext. When TRACE-level logging is...

RUSTSEC-2023-0035 Adverserial use of `make_bitflags!` macro can cause undefined behavior

The macro relied on an expression of the form Enum::Variant always being a variant of the enum. However, it may also be an associated integer constant, in which case there's no guarantee that the value of said constant consists only of bits valid for this bitflag type. Thus, code like this could...

RUSTSEC-2023-0034 Resource exhaustion vulnerability in h2 may lead to Denial of Service (DoS)

If an attacker is able to flood the network with pairs of HEADERS/RSTSTREAM frames, such that the h2 application is not able to accept them faster than the bytes are received, the pending accept queue can grow in memory usage. Being able to do this consistently can result in excessive memory use,...

RUSTSEC-2023-0033 Parsing borsh messages with ZST which are not-copy/clone is unsound

Affected versions of borsh cause undefined behavior when zero-sized-types ZST are parsed and the Copy/Clone traits are not implemented/derived. For instance if 1000 instances of a ZST are deserialized, and the ZST is not copy this can be achieved through a singleton, then accessing/writing to...

RUSTSEC-2023-0029 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...

RUSTSEC-2023-0030 `Versionize::deserialize` implementation for `FamStructWrapper<T>` is lacking bound checks, potentially leading to out of bounds memory accesses

An issue was discovered in the Versionize::deserialize implementation provided by the versionize crate for vmmsysutil::fam::FamStructWrapper, which can lead to out of bounds memory accesses. The impact started with version 0.1.1. The issue was corrected in version 0.1.10 by inserting a check that...

RUSTSEC-2023-0032 Unsound FFI: Wrong API usage causes write past allocated area

The following usage causes undefined behavior. rust let kp: ntru::types::KeyPair = …; kp.getpublic.exportDefault::default When compiled with debug assertions, the code above will trigger a attempt to subtract with overflow panic before UB occurs. Other mistakes e.g. using EncParams from a differe...

maligned::alignfirst manually allocates with an alignment larger than T, and then uses Vec::fromrawparts on that allocation to get a Vec.

RUSTSEC-2023-0016 Possible out-of-bounds read in release mode

Affected versions of this crate were using a debug assertion to validate the last parameter of partialsort. This would allow invalid inputs to cause an out-of-bounds read instead of immediately panicking, when compiled without debug assertions. All writes are bounds-checked, so the out-of-bounds...

RUSTSEC-2023-0014 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...

RUSTSEC-2023-0013 `NULL` dereference during PKCS7 data verification

RUSTSEC-2023-0012 `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...

RUSTSEC-2023-0011 Invalid pointer dereference in `d2i_PKCS7` functions

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...
