1 CVE-2019-9948 254 Bypass 2019-03-23 2019-05-10
6.4
None Remote Low Not required Partial Partial None
urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call.
2 CVE-2019-9947 93 2019-03-23 2019-05-22
4.3
None Remote Medium Not required None Partial None
An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.2. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the query string or PATH_INFO) followed by an HTTP header or a Redis command. This is similar to CVE-2019-9740.
3 CVE-2019-9740 93 2019-03-12 2019-05-22

Python Software Foundation Python (CPython) version 2.7 contains a CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in shutil module (make_archive function) that can result in Denial of service, Information gain via injection of arbitrary files on the system or entire drive. This attack appear to be exploitable via Passage of unfiltered user input to the function. This vulnerability appears to have been fixed in after commit add531a1e55b0a739b0f42582f1c9747e5649ace.
5 CVE-2018-1061 399 DoS 2018-06-19 2019-05-22
5.0
None Remote Low Not required None None Partial
python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in the difflib.IS_LINE_JUNK method. An attacker could use this flaw to cause denial of service.
6 CVE-2018-1060 399 DoS 2018-06-18 2019-05-22
5.0
None Remote Low Not required None None Partial
python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in pop3lib's apop() method. An attacker could use this flaw to cause denial of service.
7 CVE-2016-2183 200 +Info 2016-08-31 2019-05-20
5.0
None Remote Low Not required Partial None None
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
8 CVE-2014-9365 2014-12-12 2018-01-04
5.8
None Remote Medium Not required Partial Partial None
The HTTP clients in the (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib libraries in CPython (aka Python) 2.x before 2.7.9 and 3.x before 3.4.3, when accessing an HTTPS URL, do not (a) check the certificate against a trust store or verify that the server hostname matches a domain name in the subject's (b) Common Name or (c) subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
9 CVE-2014-7185 189 Overflow +Info 2014-10-08 2018-01-04
6.4
None Remote Low Not required Partial None Partial
Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a "buffer" function.
10 CVE-2014-1912 119 1 Exec Code Overflow 2014-02-28 2018-01-04
7.5
None Remote Low Not required Partial Partial Partial
Buffer overflow in the socket.recvfrom_into function in Modules/socketmodule.c in Python 2.5 before 2.7.7, 3.x before 3.3.4, and 3.4.x before 3.4rc1 allows remote attackers to execute arbitrary code via a crafted string.
11 CVE-2013-7040 310 DoS 2014-05-19 2016-11-28
4.3
None Remote Medium Not required None None Partial
Python 2.7 before 3.4 only uses the last eight bits of the prefix to randomize hash values, which causes it to compute hash values without restricting the ability to trigger hash collisions predictably and makes it easier for context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1150.
12 CVE-2013-4238 20 2013-08-17 2018-10-30
4.3
None Remote Medium Not required None Partial None
The ssl.match_hostname function in the SSL module in Python 2.6 through 3.4 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
13 CVE-2012-1150 310 DoS 2012-10-05 2013-10-30
5.0
None Remote Low Not required None None Partial
Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before 3.2.3 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.
14 CVE-2012-0845 399 DoS 2012-10-05 2013-10-30
5.0
None Remote Low Not required None None Partial
SimpleXMLRPCServer.py in SimpleXMLRPCServer in Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before 3.2.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an XML-RPC POST request that contains a smaller amount of data than specified by the Content-Length header.
15 CVE-2011-4944 264 2012-08-27 2013-10-30
1.9
None Local Medium Not required Partial None None
Python 2.6 through 3.2 creates ~/.pypirc with world-readable permissions before changing them after data has been written, which introduces a race condition that allows local users to obtain a username and password by reading this file.
16 CVE-2011-4940 79 XSS 2012-06-27 2013-05-14
2.6
None Remote High Not required None Partial None
The list_directory function in Lib/SimpleHTTPServer.py in SimpleHTTPServer in Python before 2.5.6c1, 2.6.x before 2.6.7 rc2, and 2.7.x before 2.7.2 does not place a charset parameter in the Content-Type HTTP header, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 via UTF-7 encoding.
17 CVE-2011-1521 399 DoS +Info 2011-05-24 2014-02-20
6.4
None Remote Low Not required Partial None Partial
The urllib and urllib2 modules in Python 2.x before 2.7.2 and 3.x before 3.2.1 process Location headers that specify redirection to file: URLs, which makes it easier for remote attackers to obtain sensitive information or cause a denial of service (resource consumption) via a crafted URL, as demonstrated by the file:///etc/passwd and file:///dev/zero URLs.
18 CVE-2010-3493 362 DoS 2010-10-19 2017-09-18
4.3
None Remote Medium Not required None None Partial
Multiple race conditions in smtpd.py in the smtpd module in Python 2.6, 2.7, 3.1, and 3.2 alpha allow remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected return value of None, an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, or the getpeername function having an ENOTCONN error, a related issue to CVE-2010-3492.
19 CVE-2010-3492 DoS 2010-10-19 2017-09-18
5.0
None Remote Low Not required None None Partial
The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that terminate these applications via network connections.
20 CVE-2010-2089 119 DoS Overflow Mem. Corr. 2010-05-27 2013-05-14
5.0
None Remote Low Not required None None Partial
The audioop module in Python 2.7 and 3.2 does not verify the relationships between size arguments and byte string lengths, which allows context-dependent attackers to cause a denial of service (memory corruption and application crash) via crafted arguments, as demonstrated by a call to audioop.reverse with a one-byte string, a different vulnerability than CVE-2010-1634.
21 CVE-2010-1634 189 DoS Overflow 2010-05-27 2013-05-14
5.0
None Remote Low Not required None None Partial
Multiple integer overflows in audioop.c in the audioop module in Python 2.6, 2.7, 3.1, and 3.2 allow context-dependent attackers to cause a denial of service (application crash) via a large fragment, as demonstrated by a call to audioop.lin2lin with a long string in the first argument, leading to a buffer overflow. NOTE: this vulnerability exists because of an incorrect fix for CVE-2008-3143.5.
