Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Ledger Wallet Chrome app handles Bitcoin malleability attack

We have published the v1.4.3 of our Chrome app which among other things handles the Bitcoin malleability attack.
This attack was disrupting the wallet by displaying double spent transactions and showing an incorrect balance. While the funds never were at risk, the display glitches were quite unsettling and a fix was necessary in order to filter the invalid transactions.

Bitcoin Malleability Attack - Blockchain.info [help]

Hello folks, I recently made a transaction using my blockchain wallet - I sent coins to an address and about six minutes later another transaction popped up for the same amount. As far as I can gather this is the high-s/low-s malleability attack that is currently underway.
At the moment my blockchain wallet is indicating that balance is lower than what it should be (eg, it's accounting for both transactions of coins sent).
One of the transactions has 4+ confirmations, the other of course is unconfirmed.
Will my blockchain wallet correct itself and restore my balance to what it should be? Is there any intervention necessary? What should I do?
Thanks in advance for the help.
