Dist Mageia Esm H88
Mageia has issued new bitcoin packages addressing security issues such as unencrypted wallet information and potential denial-of-service risks.
Multiple vulnerabilities have been discovered in Bitcoin

Summary

Multiple vulnerabilities have been discovered in Bitcoin.
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 (CVE-2019-15947).
Bitcoin Core 0.20.0 allows remote denial of service (CVE-2020-14198).
