Disclosure of netsplit due to malicious P2P messages by first 200 peers (≤ version 0.20.1)
Disclosure of the details of an integer overflow bug which risked causing a network split, a fix for which was released on January 15th, 2021 in Bitcoin Core version 0.21.0. This issue is considered Medium severity. Technical details A network split vulnerability resulted from two separate bugs in the processing code of version messages: * Signed-integer overflow when calculating the time offset for newly connecting peers. * abs64 logic bug (abs64(std::numeric_limits::min()) == std::numeric_limits::min()), resulting in a bypass of the maximum time adjustment limit. The two bugs allow an attacker to force a victims adjusted time (system time + network time offset) to be skewed such that any new blocks are rejected for having a timestamp that is dated too far in the future. It should be noted that this attack assumes the attacker is among the first 200 peers to connect to the victim, as only the time offsets from those initial connections are factored into adjusted time. Attribution Credit goes to practicalswift for discovering and providing the initial fix for the vulnerability, and Pieter Wuille for the fix as well as general cleanup to the at-risk code. Timeline * 2020-10-10 Initial report send to [email protected] * 2020-10-13 Fix merged into Bitcoin Core (https://github.com/bitcoin/bitcoin/pull/20141) * 2021-01-15 v0.21.0 released * 2022-04-25 The last vulnerable Bitcoin Core version (0.20.x) goes EOL * 2024-07-03 Public disclosure http://dlvr.it/T96bjM

Disclosure of CPU/memory DoS due to many malicious peers (≤ version 0.20.0)
Bitcoin Core maintained an unlimited list of banned IP addresses and performed a quadratic operation on it. This could lead to an OOM crash and a CPU Dos. This issue is considered High severity. Details Bitcoin Core maintained a list of banned IP addresses. This list was not bounded and could be manipulated by an adversary. Adding new entries to this list was particularly cheap for an attacker when considering IPV6. In addition, when receiving a GETADDR message, Bitcoin Core would scan the entire ban list for every single address to be returned (up to 2500). Attribution Calin Culianu first responsibly disclosed it. Calin later publicly disclosed the bug in a PR comment. On the same day Jason Cox from Bitcoin ABC emailed the Bitcoin Core project to share this same report they also received. Timeline * 2020-06-08 Calin Culianu privately reports the bug to the Bitcoin Core project * 2020-06-08 Jason Cox privately shares the (same) report sent to Bitcoin ABC with Bitcoin Core * 2020-06-08 Calin Culianu publicly discloses the vulnerability on the original PR which introduced the quadratic behaviour * 2020-06-09 Pieter Wuille opens PR #19219 which fixes both the unbounded memory usage and the quadratic behaviour * 2020-06-16 Luke Dashjr gets assigned CVE-2020-14198 for this vulnerability after his request * 2020-07-07 Pieter’s PR is merged * 2020-08-01 Bitcoin Core 0.20.1 is released with the fix * 2021-01-14 Bitcoin Core 0.21.0 is released with the fix * 2022-04-25 The last vulnerable Bitcoin Core version (0.20.0) goes EOL * 2024-07-03 (Official) Public Disclosure http://dlvr.it/T96bj1

Rust Compiler Performance Triage
A good week overall, with a broad set of improvements to many primary benchmarks. The main single source of primary regressions is from rollup PR #111869; we are in the process of narrowing that down to see if there is a root cause.
Triage done by @pnkfelix. Revision range: cda5becc..1221e43b
3 Regressions, 3 Improvements, 3 Mixed; 4 of them in rollups 26 artifact comparisons made in total

Approved RFCs
Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:
The #[diagnostic] attribute namespace
Final Comment Period
Every week, the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now.
RFCs
[disposition: merge] Return position impl Trait in traits
[disposition: merge] eRFC: single-file packages ("cargo script") integration
Tracking Issues & PRs
[disposition: merge] rustdoc: search for slices and arrays by type with []
[disposition: close] dyn Trait comparison should not include the vtable pointer
[disposition: merge] Uplift clippy::fn_null_check lint

Call for Testing
An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:
Add a [lints] table to Cargo.toml (Feature: manifest-lint)
Tracking Issue
Testing steps
If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Disclosure of censoring unconfirmed transactions to a specific victim (≤ version 0.20.2)
An attacker could prevent a node from seeing a specific unconfirmed transaction. This issue is considered Medium severity. Details Before this issue was fixed in PR 19988, the “g_already_asked_for” mechanism was used to schedule GETDATA requests for transactions. The SendMessages() function would send out GETDATAs for transactions recently announced by peers, remembering when that request was sent out in g_already_asked_for. However, this g_already_asked_for was a “limitedmap” data structure, with a bounded size that would forget the oldest entries if it reaches 50000 entries. This makes the following attack possible: * The attacker is the first to announce a legitimate transaction T to the victim. * The victim requests T from the attacker using GETDATA. * The attacker does not respond to GETDATA until close to the time when the victim would request T from other peers (~60 seconds). * Then, the attacker carefully spams the victim with bogus announcements, causing the victim’s g_already_asked_for to evict T. * The attacker announces T again to the victim (due to how the queueing works in m_tx_process_time, this does not need to be timed particularly accurately). * The victim, not finding T in g_already_asked_for will treat it as a new announcement, sending a new GETDATA for it to the attacker. * The attacker again does not respond to GETDATA. * etc. This way, the attacker can prevent the victim from ever requesting the transaction from anyone but the attacker. Attribution Responsibly disclosed by John Newbery, claiming discovery by Amiti Uttarwar and him. Timeline * 2020-04-03 John Newbery reports the bug in an email to Suhas Daftuar and others * 2020-05-08 John Newbery suggests an approach to fixing the bug * 2020-09-21 Pieter Wuille opens PR #19988 as a comprehensive approach to fixing this and other bugs * 2020-10-14 Pieter’s PR is merged * 2021-01-14 Bitcoin Core version 0.21.0 is released with a fix * 2022-04-25 The last vulnerable Bitcoin Core version (0.20.0) goes EOL * 2024-07-03 Public disclosure http://dlvr.it/T96bhn
