Really 发布在 比特币 0 9676


Bitcoin首席科学家Gavin Andresen在TALK中发布了最新的bitcoin-qt 0.8.4 版本更新,修正了一个关键Bug和三个安全隐患,强烈建议所有用户升级。


Bitcoin-Qt version 0.8.4 is now available from:


This is a maintenance release to fix a critical bug and three
security issues; we urge all users to upgrade.

Please report bugs using the issue tracker at github:


How to Upgrade

If you are running an older version, shut it down. Wait
until it has completely shut down (which might take a few minutes for older
versions), then run the installer (on Windows) or just copy over
/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

If you are upgrading from version 0.7.2 or earlier, the first time you
run 0.8.4 your blockchain files will be re-indexed, which will take
anywhere from 30 minutes to several hours, depending on the speed of
your machine.

0.8.4 Release notes

Security issues

An attacker could send a series of messages that resulted in
an integer division-by-zero error in the Bloom Filter handling
code, causing the Bitcoin-Qt or bitcoind process to crash.
Bloom filters were introduced with version 0.8, so versions 0.8.0
through 0.8.3 are vulnerable to this critical denial-of-service attack.

A constant-time algorithm is now used to check RPC password
guess attempts; fixes https://github.com/bitcoin/bitcoin/issues/2838

Implement a better fix for the fill-memory-with-orphan-transactions
attack that was fixed in 0.8.3. See


for a description of the weaknesses of the previous fix.

Bugs fixed

Fix multi-block reorg transaction resurrection.

Fix non-standard disconnected transactions causing mempool orphans.
This bug could cause nodes running with the -debug flag to crash.

OSX: use ‘FD_FULLSYNC’ with LevelDB, which will (hopefully!)
prevent the database corruption issues many people have
experienced on OSX.

Linux: clicking on bitcoin: links was broken if you were using
a Gnome-based desktop.

Fix a hang-at-shutdown bug that only affects users that compile
their own version of Bitcoin against Boost versions 1.50-1.52.

Other changes

Checkpoint at block 250,000 to speed up initial block downloads
and make the progress indicator when downloading more accurate.
Thanks to everybody who contributed to the 0.8.4 releases!
