KyberSlash: division timings depending on secrets

Various Kyber software libraries in various environments leak secret information into timing, specifically because these libraries include a line of code that divides a secret numerator by a public denominator, the number of CPU cycles for division in various environments varies depending on the...

Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Summary In the AES GCM implementation of decryptinplacedetached, the decrypted ciphertext i.e. the correct plaintext is exposed even if tag verification fails. Impact If a program using the aes-gcm crate's decryptinplace APIs accesses the buffer after decryption failure, it will contain a...

Fails to prohibit standard library access prior to initialization of Rust standard library runtime

Affected versions allow arbitrary caller-provided code to execute before the lifetime of main. If the caller-provided code accesses particular pieces of the standard library that require an initialized Rust runtime, such as std::io or std::thread, these may not behave as documented. Panics are...

All-Zero Key Generation on Catastrophic RNG Failure

The libcrux-ed25519 key generation samples Ed25519 secret keys from a provided CSPRNG in a loop for up to 100 attempts until a non-zero key is found. If a non-zero key could not be sampled within 100 attempts the key generation function would silently continue with an all-zero buffer as the secre...

Incorrect Output of Incremental Portable SHAKE API

The incremental squeeze functions in the portable SHAKE XOF API, when attempting to squeeze more than RATE 168 for SHAKE128, 136 for SHAKE256 bytes, performed an additional permutation of the state before producing the first output block, thus discarding the first block of RATE bytes of valid XOF...

Timing Side-Channel in AES-CCM Tag Verification in AWS-LC

Observable timing discrepancy in AES-CCM decryption in AWS-LC allows an unauthenticated user to potentially determine authentication tag validity via timing analysis. The impacted implementations are through the EVP CIPHER API: EVPaes128ccm, EVPaes192ccm, and EVPaes256ccm. Customers of AWS servic...

Underflow in aes_key_unwrap function

The aeskeyunwrap function would panic if passed a ciphertext that was too short. In a debug build, it would panic due to a subtraction underflow. In a release build, it would use the small negative quantity to allocate a vector. Since the allocator expects an unsigned quantity, the negative value...

User-defined implementations of the safe trait scratchpad::Tracking can cause heap buffer overflows

The get and set methods of the public trait scratchpad::Tracking interact with unsafe code regions in the crate, and they influence the computation of addresses returned as raw pointers. However, the trait itself is not marked as unsafe, meaning users may provide custom implementations under the...

Out of bounds write triggered by crafted coverage data

Function grcov::covdir::getcoverage uses the unsafe function getuncheckedmut without validating that the index is in bounds. This results in memory corruption, and could potentially allow arbitrary code execution provided that an attacker can feed the tool crafted coverage data...

Segmentation fault due to lack of bound check

In this case, the "fastfloat2::common::AsciiStr::first" method within the "AsciiStr" struct uses the unsafe keyword to reading from memory without performing bounds checking. Specifically, it directly dereferences a pointer offset by "self.ptr". Because of the above reason, the method accesses...

Unsound usages of `core::slice::from_raw_parts`

We consider asslice and asslicemut unsound because: the pointer with any bit patterns could be cast to the slice of arbitrary types. The pointer could be created by unsafe new and deprecated fromparts. We consider that fromparts should be removed in latest version because it will help trigger...

Unsound usages of `Vec::from_raw_parts`

The library provides a public safe API transmutevecasbytes, which incorrectly assumes that any generic type T could have stable layout, causing to uninitialized memory exposure if the users pass any types with padding bytes as T and cast it to u8 pointer. In the issue, we develop a PoC to show...

`idna` accepts Punycode labels that do not produce any non-ASCII when decoded

idna 0.5.0 and earlier accepts Punycode labels that do not produce any non-ASCII output, which means that either ASCII labels or the empty root label can be masked such that they appear unequal without IDNA processing or when processed with a different implementation and equal when processed with...

Undefined behaviour in `kvm_ioctls::ioctls::vm::VmFd::create_device`

An issue was identified in the VmFd::createdevice function, leading to undefined behavior and miscompilations on rustc 1.82.0 and newer due to the function's violation of Rust's pointer safety rules. The function downcasted a mutable reference to its struct kvmcreatedevice argument to an immutabl...

Unsound usages of `std::slice::from_raw_parts`

The library breaks the safety assumptions when using unsafe API std::slice::fromrawparts. First, when using the API in iterator implementation TempFdArrayIterator.next, generic type could be any type, which would create and pass a misaligned pointer to the unsafe API. Second, when validating the...

Denial of service because of stack overflow with malicious decompression input

A denial of service vulnerability was found in zlib-rs, triggered by specially constructed input. This input causes a stack overflow, resulting in the process using zlib-rs to crash. Impact Due to the way LLVM handles the zlib-rs codebase, tail calls were not guaranteed. This caused certain input...

Multiple soundness issues

Many functions marked as safe with non-local safety guarantees The library is also unmaintained. Alternatives For quickly parsing floating-point numbe...

Risk of use-after-free in `borrowed` reads from Python weak references

The family of functions to read "borrowed" values from Python weak references were fundamentally unsound, because the weak reference does itself not have ownership of the value. At any point the last strong reference could be cleared and the borrowed value would become dangling. In PyO3 0.22.4...

Heap Buffer overflow using c_chars_to_str function

The heap-buffer-overflow is triggered in the strlen function when handling the ccharstostr function in the dbn crate. This vulnerability occurs because the CStr::fromptr function in Rust assumes that the provided C string is null-terminated. However, there is no guarantee that the input chars arr...

Unsoundness in anstream

When given a valid UTF8 string "ö\x1b😀", the function in crates/anstream/src/adapter/strip.rs will be confused. The UTF8 bytes are \xc3\xb6 then \x1b then \xf0\x9f\x98\x80. When looping over "non-printable bytes" \x1b\xf0 will be considered as some non-printable sequence. This will produce a brok...

`XmpFile::close` can trigger UB

Affected versions of the crate failed to catch C++ exceptions raised within the XmpFile::close function. If such an exception occured, it would trigger undefined behavior, typically a process abort. This is best demonstrated in issue 230, where a race condition causes the close call to fail due t...

Apache Arrow Rust Object Store: AWS WebIdentityToken exposure in log files

Exposure of temporary credentials in logs in Apache Arrow Rust Object Store, version 0.10.1 and earlier on all platforms using AWS WebIdentityTokens. On certain error conditions, the logs may contain the OIDC token passed to AssumeRoleWithWebIdentity. This allows someone with access to the logs t...

op_panic in the base runtime can force a panic in the runtime's containing thread

Incorrect usage of `#[repr(packed)]`

The affected versions make unsafe memory accesses under the assumption that reprpacked has a guaranteed field order. The Rust specification does not guarantee this, and https://github.com/rust-lang/rust/pull/125360 1.80.0-beta starts reordering fields of reprpacked structs, leading to illegal...
