Non-constant-time mask generation and `u128` comparisons

Summary The ctutils::Choice type has mask generation functions for each unsigned integer size u8, u16, u32, u64, u128. These are const fn and therefore can't reuse the asm!-backed mask generation in the cmov crate that's otherwise used to ensure constant-time. In releases prior to v0.4.4, the...

Race condition in `tokio::time::Interval` on Tokio v1.54.0

Summary On the multi-threaded runtime, there is a race condition between Interval::polltick and the runtime's time driver. This affects Interval only. Sleep and Timeout are not affected. Details In Tokio v1.54.0, a race condition between tokio::time::Interval::polltick including .tick.await and t...

Certificate verification may accept distrusted intermediates

Affected versions may accept certificate paths containing distrusted emSign intermediate public keys when the configured trust anchors allow such paths. The private keys corresponding to these intermediates are now well known. Versions 0.103.16 and 0.104.0-alpha.8 reject paths containing these...

Missing case-insensitive matching for CSS url function

URL filtering, such as relative URLs and URL scheme limits, is not always applied when CSS sanitization is used. When the inner URL is quoted, CSS url"" is matched case-sensitively, when it should be matched case-insensitively. As a result, while url"" gets the intended domain name filtering, URL...

`zvariant` is unmaintained

The zvariant crate is no longer maintained as a standalone crate. It has been merged into zbus starting with version 6.0.0, as its wire module. Users should migrate to zbus, with its default features disabled if they only need the D-Bus wire format. Users of the GVariant format should migrate to...

Stack overflow when parsing deeply nested input in pest_grammars

Impact In affected versions, parsing deeply nested input with pestgrammars::json::JsonParser can exhaust the native stack and abort the hosting process. Applications that accept attacker-controlled JSON without suitable resource limits may therefore be vulnerable to denial of service. The reporte...

`zvariant_derive` is unmaintained

Brotli certificate decompression can allocate up to 1 GiB before authentication

The built-in Brotli certificate decompressor enabled by the non-default brotli crate feature bounded the size of the decompressed output, but accepted a peer-selected history window. Brotli's large-window extension was enabled, so a five-byte header could cause an allocation of 1 GiB. A peer can...

Buffered application data sent to outer server after ECH rejection

`Debug` impls for client session values expose TLS secrets

The Debug implementations of Tls12ClientSessionValue and Tls13ClientSessionValue were derived, and so included the TLS 1.2 master secret or TLS 1.3 resumption PSK in their output.

Unauthenticated ServerHello can downgrade later connections to classical key exchange

The client recorded the server-selected key exchange group for each server name when processing the ServerHello, before the server was authenticated. This record is used to predict which key share to send in future ClientHellos to that server name. A network attacker can answer one connection...

`AsyncFd::new` and related constructors violate I/O safety

tokio::io::unix::AsyncFd provides safe constructors new, withinterest, trynew, and trywithinterest that accept any T: AsRawFd rather than requiring proof of ownership or validity of the file descriptor. Because RawFd implements AsRawFd, safe code can construct an AsyncFd from an arbitrary or clos...

Decompression bomb in `ruzstd`: a tiny input can exhaust memory (OOM)

A crafted .zst input under 128 KB can force ruzstd to allocate several gigabytes at once, crashing the process with an out-of-memory condition. Since ruzstd is a decoder for untrusted input, a single small file is enough to take down anything decoding it. The compressed size of a block was capped...

ZipStreamReader::extract() and ZipArchive::extract() apply Unix permissions through symlinks without confining the target

Pre-shared key mode transmits the TGK in cleartext, exposing the SRTP master key

mykey implements MIKEY RFC 3830 for SRTP key exchange. Pre-shared key mode transmitted the TEK Generation Key TGK in the clear. MikeyMessage::newpskinit built its KEMAC payload with EncAlg::Null and placed the TGK in encdata verbatim. Anyone able to read a PSK-Init message therefore recovers the...

Poly1305 panics or computes a wrong tag on attacker-chosen messages of 64 bytes or more

Poly1305 in ic-cipher absorbs messages of 64 bytes or more four blocks at a time, summing four products before one reduction. From 0.2.5 to 0.2.19 the reduction kept its carries in 32-bit integers, which four summed products can overflow when the message's bytes are large. This affects Poly1305 a...

MIKEY message MAC is never verified on receive, so forged messages are accepted

mykey implements MIKEY RFC 3830 for SRTP key exchange. No receive path verified the MIKEY message authentication code. crypto::verifymac existed and was correct, but it was called only from unit tests — neither MikeyMessage::frombytes nor MikeyMessage::completepsk invoked it. newpskinit computed ...

Insecure Preservation of SUID/SGID Bits during ZIP Extraction Leading to Potential Privilege Escalation

The zip crate preserves privileged Unix permission bits SUID, SGID, and sticky bits from ZIP externalattributes during extraction, instead of masking them to safe permission bits. If a privileged process for example, root in an installer, CI/CD pipeline, or container build extracts an...

zip: `ZipArchive::extract` creates symbolic links whose attacker-controlled targets are outside the destination directory

In zip 9.0.0-pre2, ZipArchive::extract creates a symbolic link from an archive entry after validating only the output entry path. The link target bytes are passed directly to the platform symlink API, so a malicious archive can create an entry inside the destination that resolves to an...

Resource budgets not enforced on the typed deserialization path

ParserConfig::maxevents, maxnodes, maxtotalscalarbytes, maxmergekeys, aliasanchorratio and the alias jump factor were enforced only by the two Value loaders. A typed target with a default-shaped configuration is served by the streaming deserializer, which never read those fields, so tightening an...
