Previously, when a runtime reported an unhandled exception, only the runtime-provided stack trace was captured; no native stacks were collected for any thread because PR_SET_PTRACER was not set for unhandled exceptions. Additionally, when all-thread collection was enabled for signal-based crashes, the crashing thread was excluded from the threads array.
This change:
Enables native stack collection for all threads (including the crashing thread) when reporting unhandled exceptions with collect_all_threads enabled. The receiver now has the necessary ptrace permissions to unwind every thread in the process.
Includes the crashing thread in the error.threads array (marked with crashed: true) for both signal-based crashes and unhandled exceptions. Its native stack is collected by the receiver using ptrace, same as every other thread.
The runtime-provided stack remains in error.stack as the canonical crash context, while error.threads provides a uniform native view of all threads at the time of the crash.
This gives us two immediate benefits:
Unhandled exception crash reports now include native stacks for all threads, providing visibility into what the process was doing at the OS level; not just the managed runtime view.
The crashing thread's native stack is now collected in the receiver alongside all other threads, establishing a path toward consolidating all stack collection in the receiver process in the future.

error[vulnerability]: NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses

├ ID: RUSTSEC-2026-0118
├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0118
├ 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 SOA name. When the SOA in a response's authority section
is not an ancestor of the QNAME, the loop stalls at the DNS root and never
terminates, repeatedly calling `Name::base_name()` and pushing newly allocated
`Name` and hashed-name entries into the candidate `Vec`.
The bug is reachable by any caller of `DnssecDnsHandle` — including the
resolver, recursor, and client — when built with the `dnssec-ring` or
`dnssec-aws-lc-rs` feature and configured to perform DNSSEC validation. It is
triggered while validating a NoData or NXDomain response whose authority
section contains an SOA record from a zone other than an ancestor of the
QNAME, on a code path that requires NSEC3 closest-encloser proof. In practice
this can be reached through an insecure CNAME chain that crosses zone
boundaries into a DNSSEC-signed zone returning NoData, but the minimum
condition is just a mismatched SOA owner on a response requiring NSEC3
validation.
A `debug_assert_ne!(name, Name::root())` guards the loop body, so debug builds
abort with a panic on the first iteration past the root. Release builds
compile the assertion out and run the loop unbounded, allocating until the
process exhausts available memory (OOM). A reachable upstream attacker who
can return such a response can therefore crash a debug-built validator or
exhaust memory on a release-built one.
The affected code was migrated from `hickory-proto` to `hickory-net` as part of
the 0.26.0 release. The `hickory-proto` 0.26.x release no longer offers
`DnssecDnsHandle` and so we recommend all affected users update to `hickory-net`
0.26.1 when the implementation of that type is required.

error[vulnerability]: CPU exhaustion during message encoding due to O(n²) name compression

├ ID: RUSTSEC-2026-0119
├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0119
├ During message encoding, `hickory-proto`'s `BinEncoder` stores pointers to
labels that are candidates for name compression in a `Vec<(usize, Vec<u8>)>`.
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 linear scan many times. This can amplify CPU exhaustion in DoS
attacks.
This is similar to
[CVE-2024-8508](https://www.nlnetlabs.nl/downloads/unbound/CVE-2024-8508.txt).

├ It has been reported (by @lopopolo) that the `rand` library is [unsound](https://rust-lang.github.io/unsafe-code-guidelines/glossary.html#soundness-of-code--of-a-library) (i.e. that safe code using the public API can cause Undefined Behaviour) when all the following conditions are met:
- The `log` and `thread_rng` features are enabled
- A [custom logger](https://docs.rs/log/latest/log/#implementing-a-logger) is defined
- The custom logger accesses `rand::rng()` (previously `rand::thread_rng()`) and calls any `TryRng` (previously `RngCore`) methods on `ThreadRng`
- The `ThreadRng` (attempts to) reseed while called from the custom logger (this happens every 64 kB of generated data)
- Trace-level logging is enabled or warn-level logging is enabled and the random source (the `getrandom` crate) is unable to provide a new seed
`TryRng` (previously `RngCore`) methods for `ThreadRng` use `unsafe` code to cast `*mut BlockRng<ReseedingCore>` to `&mut BlockRng<ReseedingCore>`. When all the above conditions are met this results in an aliased mutable reference, violating the Stacked Borrows rules. Miri is able to detect this violation in sample code. Since construction of [aliased mutable references is Undefined Behaviour](https://doc.rust-lang.org/stable/nomicon/references.html), the behaviour of optimized builds is hard to predict.

├ ID: RUSTSEC-2026-0104
├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0104
├ A panic was reachable when parsing certificate revocation lists via [`BorrowedCertRevocationList::from_der`]
or [`OwnedCertRevocationList::from_der`]. This was the result of mishandling a syntactically valid empty
`BIT STRING` appearing in the `onlySomeReasons` element of a `IssuingDistributionPoint` CRL extension.
This panic is reachable prior to a CRL's signature being verified.
Applications that do not use CRLs are not affected.
Thank you to @tynus3 for the report.
├ Solution: Upgrade to >=0.103.13, <0.104.0-alpha.1 OR >=0.104.0-alpha.7 (try `cargo update -p rustls-webpki`)
├ rustls-webpki v0.103.10

What does this PR do?
Previously, when a runtime reported an unhandled exception, only the runtime-provided stack trace was captured; no native stacks were collected for any thread because
PR_SET_PTRACERwas not set for unhandled exceptions. Additionally, when all-thread collection was enabled for signal-based crashes, the crashing thread was excluded from the threads array.This change:
collect_all_threadsenabled. The receiver now has the necessary ptrace permissions to unwind every thread in the process.error.threadsarray (marked withcrashed: true) for both signal-based crashes and unhandled exceptions. Its native stack is collected by the receiver using ptrace, same as every other thread.The runtime-provided stack remains in
error.stackas the canonical crash context, whileerror.threadsprovides a uniform native view of all threads at the time of the crash.This gives us two immediate benefits:
