1 CVE-2013-5700 189 DoS 2013-09-10 2013-09-13
5.0
None Remote Low Not required None None Partial
The Bloom Filter implementation in bitcoind and Bitcoin-Qt 0.8.x before 0.8.4rc1 allows remote attackers to cause a denial of service (divide-by-zero error and daemon crash) via a crafted sequence of messages.
2 CVE-2013-4627 DoS 2013-08-02 2013-10-11
5.0
None Remote Low Not required None None Partial
Unspecified vulnerability in bitcoind and Bitcoin-Qt 0.8.x allows remote attackers to cause a denial of service (memory consumption) via a large amount of tx message data.
3 CVE-2013-4165 200 +Info 2013-08-02 2013-10-11
4.3
None Remote Medium Not required Partial None None
The HTTPAuthorized function in bitcoinrpc.cpp in bitcoind 0.8.1 provides information about authentication failure upon detecting the first incorrect byte of a password, which makes it easier for remote attackers to determine passwords via a timing side-channel attack.
4 CVE-2013-3220 399 DoS 2013-08-02 2013-10-11
6.4
None Remote Low Not required None Partial Partial
bitcoind and Bitcoin-Qt before 0.4.9rc2, 0.5.x before 0.5.8rc2, 0.6.x before 0.6.5rc2, and 0.7.x before 0.7.3rc2, and wxBitcoin, do not properly consider whether a block's size could require an excessive number of database locks, which allows remote attackers to cause a denial of service (split) and enable certain double-spending capabilities via a large block that triggers incorrect Berkeley DB locking.
5 CVE-2013-3219 264 Bypass 2013-08-02 2013-10-11
5.0
None Remote Low Not required None Partial None
bitcoind and Bitcoin-Qt 0.8.x before 0.8.1 do not enforce a certain block protocol rule, which allows remote attackers to bypass intended access restrictions and conduct double-spending attacks via a large block that triggers incorrect Berkeley DB locking in older product versions.
6 CVE-2013-2293 399 DoS 2013-03-12 2013-03-18
5.0
None Remote Low Not required None None Partial
The CTransaction::FetchInputs method in bitcoind and Bitcoin-Qt before 0.8.0rc1 copies transactions from disk to memory without incrementally checking for spent prevouts, which allows remote attackers to cause a denial of service (disk I/O consumption) via a Bitcoin transaction with many inputs corresponding to many different parts of the stored block chain.
7 CVE-2013-2292 399 DoS 2013-03-12 2013-03-18
7.8
None Remote Low Not required None None Complete
bitcoind and Bitcoin-Qt 0.8.0 and earlier allow remote attackers to cause a denial of service (electricity consumption) by mining a block to create a nonstandard Bitcoin transaction containing multiple OP_CHECKSIG script opcodes.
8 CVE-2013-2273 200 +Info 2013-03-12 2013-03-18
5.0
None Remote Low Not required Partial None None
bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 make it easier for remote attackers to obtain potentially sensitive information about returned change by leveraging certain predictability in the outputs of a Bitcoin transaction.
9 CVE-2013-2272 200 +Info 2013-03-12 2013-03-18
5.0
None Remote Low Not required Partial None None
The penny-flooding protection mechanism in the CTxMemPool::accept method in bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 allows remote attackers to determine associations between wallet addresses and IP addresses via a series of large Bitcoin transactions with insufficient fees.
10 CVE-2012-4684 399 DoS 2013-03-12 2013-03-18
7.8
None Remote Low Not required None None Complete
The alert functionality in bitcoind and Bitcoin-Qt before 0.7.0 supports different character representations of the same signature data, but relies on a hash of this signature, which allows remote attackers to cause a denial of service (resource consumption) via a valid modified signature for a circulating alert.
11 CVE-2012-4683 DoS 2012-09-14 2012-09-17
5.0
None Remote Low Not required None None Partial
Unspecified vulnerability in bitcoind and Bitcoin-Qt allows attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2012-4682.
12 CVE-2012-4682 DoS 2012-09-14 2012-09-17
5.0
None Remote Low Not required None None Partial
Unspecified vulnerability in bitcoind and Bitcoin-Qt allows attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2012-4683.
13 CVE-2012-3789 DoS 2012-08-06 2012-08-07
5.0
None Remote Low Not required None None Partial

15 CVE-2012-1910 DoS Exec Code 2012-08-06 2012-08-07
7.5
None Remote Low Not required Partial Partial Partial
Bitcoin-Qt 0.5.0.x before 0.5.0.5; 0.5.1.x, 0.5.2.x, and 0.5.3.x before 0.5.3.1; and 0.6.x before 0.6.0rc4 on Windows does not use MinGW multithread-safe exception handling, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted Bitcoin protocol messages.
16 CVE-2012-1909 16 DoS 2012-08-06 2012-08-07
5.0
None Remote Low Not required None None Partial
The Bitcoin protocol, as used in bitcoind before 0.4.4, wxBitcoin, Bitcoin-Qt, and other programs, does not properly handle multiple transactions with the same identifier, which allows remote attackers to cause a denial of service (unspendable transaction) by leveraging the ability to create a duplicate coinbase transaction.
17 CVE-2011-4447 310 Bypass 2012-08-06 2012-08-07
4.3
None Remote Medium Not required Partial None None
The "encrypt wallet" feature in wxBitcoin and bitcoind 0.4.x before 0.4.1, and 0.5.0rc, does not properly interact with the deletion functionality of BSDDB, which allows context-dependent attackers to obtain unencrypted private keys from Bitcoin wallet files by bypassing the BSDDB interface and reading entries that are marked for deletion.
18 CVE-2010-5141 264 2012-08-06 2012-08-07
7.5
None Remote Low Not required Partial Partial Partial

5.0
None Remote Low Not required None None Partial
wxBitcoin and bitcoind before 0.3.13 do not properly handle bitcoins associated with Bitcoin transactions that have zero confirmations, which allows remote attackers to cause a denial of service (invalid-transaction flood) by sending low-valued transactions without transaction fees.

7.5
None Remote Low Not required Partial Partial Partial
