VulnerabilityTitle and contextCVSSEPSSPoCsSignalsSTIX action

Bitcoin-Qt in Bitcoin Core before 0.20.0 allows remote attackers to cause a denial of service (memory consumption and application crash) via a BIP21 r parameter for a URL that has a large file.

CWE-770Nov 18, 2024
CVSS6.5v3.1EPSS0.471%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 22.0 has a miniupnp infinite loop in which it allocates memory on the basis of random data received over the network, e.g., large M-SEARCH replies from a fake UPnP device.

CWE-770Nov 18, 2024
CVSS6.5v3.1EPSS0.267%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 0.21.0 allows a network split that is resultant from an integer overflow (calculating the time offset for newly connecting peers) and an abs64 logic bug.

CWE-190Nov 18, 2024
CVSS7.5v3.1EPSS0.518%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 22.0 has a CAddrMan nIdCount integer overflow and resultant assertion failure (and daemon exit) via a flood of addr messages.

CWE-190Nov 18, 2024
CVSS6.5v3.1EPSS0.266%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

In Bitcoin Core before 25.1, an attacker can cause a node to not download the latest block, because there can be minutes of delay when an announcing peer stalls instead of complying with the peer-to-peer protocol specification.

CVSS6.5v3.1EPSS0.315%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

In Bitcoin Core before 25.0, a peer can affect the download state of other peers by sending a mutated block.

CWE-862Nov 18, 2024
CVSS5.3v3.1EPSS0.428%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 0.20.0 allows remote attackers to cause a denial of service (memory consumption) via a crafted INV message.

CWE-770Nov 18, 2024
CVSS7.5v3.1EPSS0.62%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

In Bitcoin Core before 0.18.0, a node could be stalled for hours when processing the orphans of a crafted unconfirmed transaction.

CWE-770Nov 18, 2024
CVSS7.5v3.1EPSS0.509%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

In Bitcoin Core before 0.21.0, an attacker could prevent a node from seeing a specific unconfirmed transaction, because transaction re-requests are mishandled.

CWE-770Nov 18, 2024
CVSS5.3v3.1EPSS0.366%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 0.15.0 allows a denial of service (OOM kill of a daemon process) via a flood of minimum difficulty headers.

CWE-770Nov 18, 2024
CVSS7.5v3.1EPSS0.509%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 24.0.1 allows remote attackers to cause a denial of service (daemon crash) via a flood of low-difficulty header chains (aka a "Chain Width Expansion" attack) because a node does not first verify that a presented chain has enough work before committing to store it.

CWE-770Nov 18, 2024
CVSS7.5v3.1EPSS0.783%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

miniupnp before 4c90b87, as used in Bitcoin Core before 0.12 and other products, lacks checks for snprintf return values, leading to a buffer overflow and significant data leak, a different vulnerability than CVE-2019-12107. In Bitcoin Core before 0.12, remote code execution was possible in conjunction with CVE-2015-6031 exploitation.

CWE-120Nov 18, 2024
CVSS9.8v3.1EPSS1.27%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core before 0.20.0 allows remote attackers to cause a denial of service (infinite loop) via a malformed GETDATA message.

CWE-770Nov 18, 2024
CVSS7.5v3.1EPSS0.607%PoCs0SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templatesSTIX

Bitcoin Core and Bitcoin Knots Datacarrier Size Limit Bypass Vulnerability

In Bitcoin Core through 26.0 and Bitcoin Knots before 25.1.knots20231115, datacarrier size limits can be bypassed by obfuscating data as code (e.g., with OP_FALSE OP_IF), as exploited in the wild by Inscriptions in 2022 and 2023. NOTE: although this is a vulnerability from the perspective of the Bitcoin Knots project, some others consider it "not a bug."

bitcoin bitcoin_core Uncontrolled Resource Consumption

Bitcoin Core before 24.1, when debug mode is not used, allows attackers to cause a denial of service (e.g., CPU consumption) because draining the inventory-to-send queue is inefficient, as exploited in the wild in May 2023.

CWE-400May 22, 2023
