Descriptions

In Bitcoin Core 0.18.0, bitcoin-qt stores wallet.dat data unencrypted in memory. Upon a crash, it may dump a core file. If a user were to mishandle a core file, an attacker can reconstruct the user's wallet.dat file, including their private keys, via a grep "6231 0500" command.

En Bitcoin Core versión 0.18.0, bitcoin-qt almacena los datos de wallet.dat sin cifrar en la memoria. Ante un bloqueo, puede volcar un archivo core. Si un usuario gestiona de manera incorrecta un archivo core, un atacante puede reconstruir el archivo wallet.dat del usuario, incluidas sus claves privadas, mediante un comando grep "6231 0500".

Multiple vulnerabilities have been found in Bitcoin, the worst of which could result in a Denial of Service condition. Versions less than 0.20.1 are affected.
