enum_map macro can cause UB when `Enum` trait is incorrectly implemented

Affected versions of this crate did not properly check the length of an enum when using enummap! macro, trusting user-provided length. When the LENGTH in the Enum trait does not match the array length in the EnumArray trait, this can result in the initialization of the enum map with uninitialized...

Memory access due to code generation flaw in Cranelift module

There is a bug in 0.73.0 of the Cranelift x64 backend that can create a scenario that could result in a potential sandbox escape in a WebAssembly module. Users of versions 0.73.0 of Cranelift should upgrade to either 0.73.1 or 0.74 to remediate this vulnerability. Users of Cranelift prior to 0.73...

Uncontrolled recursion leads to abort in deserialization

Affected versions of this crate did not properly check for recursion while deserializing aliases. This allows an attacker to make a YAML file with an alias referring to itself causing an abort. The flaw was corrected by checking the recursion depth...

quickersort is deprecated and unmaintained

The author of the quickersort crate has deprecated it and does not recommend using it anymore. Everything in it has been incorporated into std::sortunstable in the standard library as of Rust 1.20. std::sortunstable: https://doc.rust-lang.org/stable/std/primitive.slice.htmlmethod.sortunstable...

Panic-safety unsoundness in `BitVecCore::clear` (double-free / use-after-free)

BitVecCore::clear drops every occupied element with dropinplace and only afterwards clears the occupancy bits and resets len. If an element's Drop panics, those metadata updates are skipped, so the slot of the already-dropped element stays marked as occupied. BitVecCore::drop calls clear again,...

`tinymember` was removed from crates.io due to affiliation with malicious code

While tinymember did not directly contain malicious code, it was owned by the same user as arone and aronenao, which contained suspicious build scripts.

Uint shift operations: incorrect overflow flags and truncated shift amounts

Uint::overflowingshl/overflowingshr returned false-negative overflow flags. overflowingshl missed bits shifted above BITS but within the top limb non-limb-aligned widths such as U160, and limbs wholly discarded by shifts = 64; overflowingshr missed wholly discarded low limbs. Shifted values were...

Invalid pointer dereference in `fmt::Pointer` impl for `Atomic` and `Shared` when the underlying pointer is invalid

Affected versions of fmt::Display dereference the underlying pointer. This causes a invalid pointer dereference e.g., when a pointer created with Atomic::null or Shared::null. fmt::Debug impls and pre-0.9 fmt::Display impls, which do not dereference pointers, are not affected by this issue...

Integer overflow in tract-nnef NNEF tensor parser leads to out-of-bounds read on model load

tractnnef::tensors::readtensor builds a tensor shape from attacker-controlled 32-bit dimensions and computes both the element count productshape and the byte allocation productshape sizeofdt with unchecked usize arithmetic. In release builds no overflow-checks both products wrap modulo 2^64. A...

Incorrect Check of Signer Response Norm During Verification

The ML-DSA verification algorithm as specified in FIPS 204, subsection 6.3 requires verifiers to check that the infinity norm of the deserialized signer response $z$ does not exceed $\gamma1 - \beta$ line 13 of Algorithm 8. The same check is required to be performed during signature generation...

Uninitialized memory exposure in create_ring_buffer

The safe function createringbuffer allocates a buffer using Vec::withcapacity followed by setlen, creating a Box containing uninitialized memory. This leads to undefined behavior when functions like writeslices create typed slices e.g., &mut bool over the uninitialized memory, violating Rust's...

Out-of-bounds memory access in binary_read_to_ref and binary_write_from_ref

Safe functions accept a single &T or &mut T but multiply by n to create slices extending beyond allocated memory when n 1. These functions use fromrawparts to create slices larger than the underlying allocation, violating memory safety. The binaryvecio repository is archived and unmaintained...

`root` appended to group listings

Affected versions append root to group listings, unless the correct listing has exactly 1024 groups. This affects both: - The supplementary groups of a user - The group access list of the current process If the caller uses this information for access control, this may lead to privilege escalation...

Segmentation fault due to lack of bound check

In this case, the "fastfloat::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...

`Endpoint::retry()` calls can lead to panicking

In 0.11.0, we overhauled the server-side Endpoint implementation to enable more careful handling of incoming connection attempts. However, some of the code paths that cleaned up state after connection attempts were processed confused the initial destination connection ID with the destination...

`postgress` was removed from crates.io for malicious code

This crate was part of a typosquatting malware cluster published by the malicious user amaperf and contained a malware payload in build.rs to exfiltrate host information to the attacker.

Invalid use of `mem::uninitialized` causes `use-of-uninitialized-value`

The compression and decompression function used mem:uninitialized to create an array of uninitialized values, to later write values into it. This later leads to reads from uninitialized memory. The flaw was corrected in commit b633bf265e41c60dfce3be7eac4e4dd5e18d06cf by using a heap-allocated Vec...

A malicious coder can get unsound access to TCell or TLCell memory

This is impossible to do by accident, but by carefully constructing marker types to be covariant, a malicious coder can cheat the singleton check in TCellOwner and TLCellOwner, giving unsound access to cell memory. This could take the form of getting two mutable references to the same memory, or ...

Improper validation of Windows paths could lead to directory traversal attack

Path resolution in warp::filters::fs::dir 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. Th...
