Flaw in CBOR deserializer allows stack overflow

Affected versions of this crate did not properly check if semantic tags were nested excessively during deserialization. This allows an attacker to craft small 1 kB CBOR documents that cause a stack overflow. The flaw was corrected by limiting the allowed number of nested tags...

`boxfnonce` obsolete with release of Rust 1.35.0

This commit marks the boxfnonce crate as obsolete and the GitHub repo has since been archived. The functionality of boxfnonce has been added to Rust since 1.35.0. Use Box...

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...

Remote Denial of Service via malformed NIP‑44 v2 payload

The NIP-44 v2 decryption path in the nostr crate contains a reachable panic when processing a short or empty ciphertext. After the HMAC check passes and the ciphertext is decrypted via ChaCha20, the code reads a 2‑byte unpadded‑length prefix via buffer0..2 without first verifying that the decrypt...

Potential undefined behavior with Signature from a buffer-created BlameHunk

When a Blame is created via Blame::blamebuffer, and a BlameHunk is retrieved, the pointers to the original author, original committer, final author, and final committer may be null if unavailable. The corresponding BlameHunk methods then create Signatures based on null pointers; attempting to...

smartstring is unmaintained

Double-free in `Chomp::inner()`

Chomp::inner uses std::ptr::readunaligned to move out the value from a raw pointer. If the original value is an owned type e.g. Box, calling inner moves out the ownership, but the original variable will still be dropped at the end of its scope. This causes the same heap memory to be freed twice,...

Fragile bounds check when sampling from image

A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered NaN cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected...

`unpack_in` can chmod arbitrary directories by following symlinks

In versions 0.4.44 and below of tar-rs, when unpacking a tar archive, the tar crate's unpackdir function uses fs::metadatafs-metadata to check whether a path that already exists is a directory. Because fs::metadata follows symbolic links, a crafted tarball containing a symlink entry followed by a...

Insufficient validation of PAX extensions during extraction

In versions 0.5.6 and earlier of astral-tokio-tar, malformed PAX extensions were silently skipped when parsing tar archives. This silent skipping rather than rejection of invalid PAX extensions could be used as a building block for a parser differential, for example by silently skipping a malform...

Cache poisoning via insecure-by-default cache key

Pingora versions prior to 0.8.0 generated cache keys using only the URI path, excluding critical factors such as the host header. This allows an attacker to poison the cache and serve cross-origin responses to users. This vulnerability affects users of Pingora's alpha proxy caching feature who...

`dnp3times` was removed from crates.io due to malicious code

The dnp3times crate attempted to exfiltrate .env files to a server that was in turn impersonating the legitimate timeapi.io service. It was loosely trying to typosquat the dnp3time crate, but otherwise was the same attack as the timecalibrator and timecalibrators malware yesterday. The malicious...

`rpc-check` was removed from crates.io for malicious code

This is part of an ongoing campaign to attempt to typosquat crates in the polymarket-client-sdk ecosystem to exfiltrate user credentials. The malicious crate had 6 versions published from 2026-02-20 onwards and had no evidence of actual usage. There were no crates depending on this crate on...

Panic When Opening or Sealing on Export-Only Context

Constructing an HPKE Context with the AEAD algorithm set to HpkeExport resulted in a panic when calling Context::seal, or Context::open. This was due to an underflowing integer subtraction when calculating the length of a vector allocation for the AEAD nonce, which would panic on its own in debug...

Unsoundness of safe `reciprocal_mg10`

The function reciprocalmg10 is marked as safe but can trigger undefined behavior out-of-bounds access because it relies on debugassert! for safety checks instead of assert!. When compiled in release mode, the debugassert! is optimized out, potentially allowing invalid inputs to cause memory...

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

This attempts to typosquat the existing crate finchcli to steal credentials from local files. The malicious crate had 1 version published on 2025-12-08 and had been downloaded 18 times. There were no crates depending on this crate on crates.io. Thanks to Matthias Zepper of NGI Sweden for reportin...

matrix-sdk-base: Denial of service due to custom `m.room.join_rules` events

The matrix-sdk-base crate is unable to handle responses that include custom m.room.joinrules values due to a serialization bug. This can be exploited to cause a denial-of-service condition, if a user is invited to a room with non-standard join rules, the crate's sync process will stall, preventin...

Broadcast channel calls clone in parallel, but does not require `Sync`

The broadcast channel internally calls clone on the stored value when receiving it, and only requires T:Send. This means that using the broadcast channel with values that are Send but not Sync can trigger unsoundness if the clone implementation makes use of the value being !Sync. Thank you to...

Hickory DNS failure to verify self-signed RRSIG for DNSKEYs

Summary The DNSSEC validation routines treat entire RRsets of DNSKEY records as trusted once they have established trust in only one of the DNSKEYs. As a result, if a zone includes a DNSKEY with a public key that matches a configured trust anchor, all keys in that zone will be trusted to...

Use of insecure cryptographic algorithms

This crate uses a number of cryptographic algorithms that are no longer considered secure and it uses them in ways that do not guarantee the integrity of the encrypted data.

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...

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...
