NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses

The NSEC3 closest-encloser proof validation in hickory-proto's DnssecDnsHandle walks from the QNAME up to the SOA owner name, building a list of candidate encloser names. The iterator used assumes the QNAME is a descendant of the SOA owner, terminating only when the current candidate equals the S...

CPU exhaustion during message encoding due to O(n²) name compression

During message encoding, hickory-proto's BinEncoder stores pointers to labels that are candidates for name compression in a Vec. The name compression logic then searches for matches with a linear scan. A malicious message with many records can both introduce many candidate labels, and invoke this...

Fragile bounds check when sampling from image

A read of pixels was coded as modifying coordinates to lie within the image bounds. It would calculate a coordinate by adding a constant to an input and taking the minimum of the resulting coordinate and 'dimension - 1'. This would not protect against malicious inputs that could overflow the...

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...

Improper check of an invariant resulting in incorrect bounds checks

A bounds verification of a slice storage of a 2-dimensional matrix's coefficients a kernel would compare the total size against the product of individual dimensions. This would erroneously cast after the multiplication and consequently fail to detect possible violations when overflow occurs...

NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses

The NSEC3 closest-encloser proof validation in hickory-net's DnssecDnsHandle walks from the QNAME up to the SOA owner name, building a list of candidate encloser names.

Unsound access to padding bytes while serializing date/time values using the Mysql backend

Diesel-async uses the mysql-async crate for interacting with Mysql compatible databases. This library already provides access to deserialized data for date/time releated types. Diesel-async then translated these deserialized data back to their serialized binary representation to hook into diesels...

DNS rebinding vulnerability in rmcp Streamable HTTP server transport

Prior to version 1.4.0, the rmcp crate's Streamable HTTP server transport did not validate the incoming Host header. This allowed a malicious public website, via a DNS rebinding attack, to send requests to an MCP server running on the victim's loopback or private-network interface. An attacker wh...

PAX Header Desynchronization in astral-tokio-tar

Versions of astral-tokio-tar prior to 0.6.1 contain a PAX header interpretation bug that allows manipulated entries to be made selectively visible or invisible during extraction with astral-tokio-tar versus other tar implementations. An attacker could use this differential to smuggle unexpected...

AVX2 Implementation Did Not Fully Reduce Intermediate Values

The AVX2 implementation of ML-DSA did not fully reduce intermediate inputs to the inverse NTT, which leads to a testable difference in panic behaviour of internal functions compared to the portable implementation. Impact We are not aware of inputs to the public key generation, signing or...

`unpack_in` can chmod arbitrary directories by following symlinks

In versions 0.6.0 and earlier of astral-tokio-tar, the unpackin API could inadvertently modify the permissions of external i.e. non-archive directories outside of the archive. An attacker could use this to contrite a tar archive that maliciously changes directory permissions outside of its intend...

Unsound transmute while debug/display printing batch Insert statements in Diesel's SQLite backend

Diesel allows users to output the generated SQL for any query DSL construct via th diesel::debugquery function as Display and Debug output. For the particular implementation used by batch Insert statements in the SQLite backend Diesel relied on an unspecified transmute between types with a reprru...

Command injection in Diesel's implementation of `COPY FROM`/`COPY TO`

Diesel allows users to configure various options for PostgreSQL's COPY FROM and COPY TO statements. These configurations are partially provided as strings or characters. Diesel did not check if any these user-provided options contain a quote character ', which can lead to the injection of...

Possible UTF-8 corruption in Diesels SQLite backend

Diesel uses the sqlite3valuetext function to receive strings from SQLite while deserializing query results. We misinterpreted the corresponding SQLite documentation that this function always returns a UTF-8 encoded string values as const cchar. Based on that we used str::fromutf8unchecked to...

Possible unaligned data access for implementations of `SqliteAggregate`

Diesel allows to register custom aggregate SQL functions for SQLite via the SqliteAggregate interface. To store an instance of the custom aggregate processor Diesel relied on the sqlite3aggregatecontext function provided by sqlite. This function doesn't provide any guarantees about alignment of t...

Unsound access to padding bytes while serializing date/time values using the Mysql backend

Diesel relies on libmysqlclient for interacting with Mysql compatible databases. This library requires to provide date/time values according to the byte layout of their MYSQLTIME type. Diesel replicated this type as reprC struct, populated all the fields of this struct and then casted this value ...

Potential use-after-free due to lack of panic safety in `InlineVec::clear` and `SerVec::clear`

InlineVec::clear and SerVec::clear in rkyv were not panic-safe. Both functions iterate over their elements and call dropinplace on each, updating self.len only after the loop. If an element's Drop implementation panics during the loop, self.len is left at its original value. A subsequent invocati...

`sui-execution-cut` was removed from crates.io for malicious code

Record cache accepts AUTHORITY section NS from sibling zone via parent-pool zone-context elevation

The Hickory DNS project's experimental hickory-recursor crate's record cache DnsLru stores records from DNS responses keyed by each record's own name, type, not by the query that triggered the response. cacheresponse in crates/recursor/src/lib.rs chains ANSWER, AUTHORITY, and ADDITIONAL sections...

Reachable panic in certificate revocation list parsing

A panic was reachable when parsing certificate revocation lists via BorrowedCertRevocationList::fromder or OwnedCertRevocationList::fromder. This was the result of mishandling a syntactically valid empty BIT STRING appearing in the onlySomeReasons element of a IssuingDistributionPoint CRL...

Incorrect Output of Incremental Portable SHAKE API on Multiple Squeeze Calls

The incremental squeeze functions in the portable SHAKE XOF API, when attempting to squeeze an output using multiple calls to squeeze, rather than squeezing the full output at once, could output incorrect values. Internally, output blocks that were not completely squeezed were not buffered for th...

Broken hard revocation handling

Before sq-git checks if a commit can be authenticated, it first looks for hard revocations. Because parsing a policy is expensive and a project's policy rarely changes, sq-git has an optimization to only check a policy if it hasn't checked it before. It does this by maintaining a set of policies...

Name constraints for URI names were incorrectly accepted

Name constraints for URI names were ignored and therefore accepted. Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented. URI name constraints are now rejected unconditionally. Since name constraints are restrictions on otherwis...

Name constraints were accepted for certificates asserting a wildcard name

Permitted subtree name constraints for DNS names were accepted for certificates asserting a wildcard name. This was incorrect because, given a name constraint of accept.example.com, .example.com could feasibly allow a name of reject.example.com which is outside the constraint. This is very simila...

Use-After-Free and Double Free in IntoIter::drop When Element Drop Panics
