Critical Security Fixes in Dogecoin Core 1.14.6: Upgrade Guidance and Vulnerability Analysis

Security Disclosure and Network Impact

A recent security disclosure by cybersecurity firm Halborn revealed critical vulnerabilities in Dogecoin Core versions 1.14.5 and earlier. These flaws were also identified in 280 other Bitcoin-derived blockchain networks.

The Dogecoin development team collaborated privately with Halborn to address these issues, implementing fixes in Dogecoin Core 1.14.6. Key details:

• Vulnerabilities affected the peer-to-peer protocol implementation
• Low-memory nodes (≤2GB RAM) were particularly susceptible to memory exhaustion attacks
• Over 50% of the network has upgraded, reducing overall risk
• Individual unpatched nodes remain vulnerable

Upgrade Process: Step-by-Step Instructions

Standard Upgrade Path

For users running versions 1.8.x, 1.10.0, 1.14.0, or 1.14.5:

1. Download updated binaries from the official release page
2. Install the new version
3. Restart your node

Verify your version via:

• The Qt interface's lower-left corner
• Command line: dogecoind -version

Special Cases for Versions 1.14.2-1.14.4

Users of these versions who've previously used 1.14.0 may encounter stuck transactions due to a policy bug fix. Two resolution methods:

Method 1: Automatic Purge

Run your node once with:

dogecoind -zapwallettxes=1

or for GUI users:

Dogecoin-Qt.exe -zapwallettxes=1

Method 2: Manual Cleanup

Identify stuck transactions (0 confirmations) using:

dogecoin-cli listtransactions "*" 100000 0 | jq -r '.[] | select(.confirmations == 0)'

Then abandon individual transactions with:

dogecoin-cli abandontransaction TXID_HERE

Post-Upgrade Verification

After updating to 1.14.6:

1. Check for remaining stuck transactions:

   dogecoin-cli liststucktransactions

   (Should return empty brackets [] if clean)

2. Optional: Mimic 1.14.2 dust rules with:

   -harddustlimit=1
