Summary

Some miners are currently generating invalid blocks. Bitcoin Core - 0.9.x and earlier will accept these invalid blocks, making them + 0.9.4 and earlier will accept these invalid blocks, making them more vulnerable to double spends. This also applies to web wallets - from companies that still use 0.9.x or earlier nodes.

+ from companies that still use 0.9.4 or earlier nodes.

Lightweight (SPV) wallets are also at increased risk, and will remain so until all miners have switched back to full validation.

Users of the above listed vulnerable software must either stop - accepting transactions or upgrade to Bitcoin - Core 0.10.0 or later.

+ accepting transactions—even if they are confirmed— or upgrade to Bitcoin + Core 0.10.2.
