-----BEGIN PGP SIGNED MESSAGE-----Hash: SHA1A potential security vulnerability has been discovered in the Windowsversion of Bitcoin-Qt. If you are running Bitcoin-Qt versions 0.5through 0.6 on Windows you should shut it down and upgrade to eitherversion 0.5.3.1 or 0.6rc4 NOW.The command-line bitcoin daemon (bitcoind), Mac and Linux versions ofBitcoin-Qt, and versions prior to 0.5 are not affected.Due to the nature of the vulnerability, we believe it would be verydifficult for an attacker to do anything more than crash theBitcoin-Qt process. However, because there is a possibility of such acrash causing remote code execution we consider this a critical issue.Binaries are available at SourceForge:If you have questions, feel free to drop by the #bitcoin-dev channelon FreeNode IRC.- --Gavin AndresenGregory MaxwellMatt CoralloNils SchneiderWladimir J. van der Laan-----BEGIN PGP SIGNATURE-----Version: GnuPG v1.4.9 (Darwin)Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9j12IACgkQdYgkL74406iIyQCfbxFTO3yD4Q2bHDjPlDuJn3Mj9GAAn3mV+ggo+5q1Ujd0A5zwpFYojkE2=g1Ad-----END PGP SIGNATURE-----

about 3 days ago i was commenting on the language choice. from a software architecture standpoint other languages than c++ would make more sense in such a sensitive area. i am not suggesting that it should be rewritten. but i think it is very important that alternative implementations like BitcoinJ, multibit, armory, electrum exist.

For this specific bug, yes. But wxBitcoin (the GUI in 0.4.x) is not maintained or supported at all, so it likely has other unfixed vulnerabilities.

If the installer ain't working for you... Make sure you select 'Run As Administrator'. Users whom wisely don't run as a super user, will get the error 'cannot access file.' Instead of a prompt for an escalation of privileges.
