Bitcoin Core Three new vulnerabilities discovered, fixes released in multiple versions
PANews October 29 News reports, according to Bitcoin News,Bitcoin Core the program was found to have three new vulnerabilities, one of which allows attackers to remotely crash nodes. The first vulnerability enables malicious peers to crash Bitcoin nodes running Windows, macOS, or BSD by exhausting memory; Linux nodes are not affected. The second vulnerability allows attackers to gradually exhaust node memory, while the third could corrupt blockchain undo data. Two of the vulnerabilities were discovered by Project Loupe, powered by AI, at Spiral, while the other was independently identified by L0RINC. Fixes are available in Bitcoin Core 29.5、30.4、31.2 and 32.1, but certain configurations remain affected by the third issue.
Reports stated that Bitcoin Core new vulnerabilities were discovered, one of which could allow an attacker to remotely crash nodes.
02
The first vulnerability could allow a malicious peer to crash Bitcoin nodes running Windows, macOS, or by exhausting memory;BSD Linux nodes are unaffected.
03
The second vulnerability allows an attacker to gradually exhaust a node's memory.
04
The third vulnerability could corrupt blockchain undo data.
05
of the vulnerabilities were AI discovered at Spiral by Project Loupe, powered by L0RINC while the other was independently identified.
06
The fixed version is available in Bitcoin Core 29.5、30.4、31.2 and 32.1, but some configurations are still affected by a third issue.
AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
This is a report on security vulnerabilities in Bitcoin node software. Some vulnerabilities may cause nodes to crash or exhaust memory, while another may affect undo data; users should pay attention to the applicable fixed versions and configuration impacts.
Why it matters to readers
Node software vulnerabilities may affect the stability and data processing of some nodes, but current evidence does not indicate that the vulnerabilities have been exploited or that the blockchain has been compromised.
If you run a Bitcoin Core node, you should verify whether the version and configuration you use are affected and review the official security guidance.
Risks and unknowns
The current evidence is media reporting citing Bitcoin News and does not provide an Bitcoin Core official vulnerability advisory.
The evidence does not indicate whether the vulnerability has been actively exploited.
The evidence does not specify which configurations remain affected by the third vulnerability.
The evidence does not indicate whether blockchain revocation data has already been compromised.
