Subject: bitcoin: CVE-2019-15947

Date: Fri, 06 Sep 2019 21:18:30 +0200

Source: bitcoin
Version: 0.18.1~dfsg-1
Severity: grave
Tags: security upstream
Justification: user security hole

Hi,

The following vulnerability was published for bitcoin.

CVE-2019-15947[0]:
| 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.

The severity is a bit exagerated here, but given the package is only
in testing and unstable, before the buster release this might be
considered RC and needed to fix. But it's a long road to there.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.
