CVE-2019-20907 8 Canonical, Debian, Fedoraproject and 5 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2024-11-21 7.5 High
In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation.
CVE-2019-19911 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-21 7.5 High
There is a DoS vulnerability in Pillow before 6.2.2 caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.
CVE-2019-19275 1 Python 1 Typed Ast 2024-11-21 7.5 High
typed_ast 1.3.0 and 1.3.1 has an ast_for_arguments out-of-bounds read. An attacker with the ability to cause a Python interpreter to parse Python source (but not necessarily execute it) may be able to crash the interpreter process. This could be a concern, for example, in a web-based service that parses (but does not execute) Python code. (This issue also affected certain Python 3.8.0-alpha prereleases.)
CVE-2019-19274 1 Python 1 Typed Ast 2024-11-21 7.5 High
typed_ast 1.3.0 and 1.3.1 has a handle_keywordonly_args out-of-bounds read. An attacker with the ability to cause a Python interpreter to parse Python source (but not necessarily execute it) may be able to crash the interpreter process. This could be a concern, for example, in a web-based service that parses (but does not execute) Python code. (This issue also affected certain Python 3.8.0-alpha prereleases.)
CVE-2019-18348 2 Python, Redhat 2 Python, Rhel Software Collections 2024-11-21 6.1 Medium
An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. 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 host component of a URL) followed by an HTTP header. This is similar to the CVE-2019-9740 query string issue and the CVE-2019-9947 path string issue. (This is not exploitable when glibc has CVE-2016-10739 fixed.). This is fixed in: v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1; v3.6.11, v3.6.11rc1, v3.6.12; v3.7.8, v3.7.8rc1, v3.7.9; v3.8.3, v3.8.3rc1, v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1.
CVE-2019-17514 1 Python 1 Python 2024-11-21 7.5 High
library/glob.html in the Python 2 and 3 documentation before 2016 has potentially misleading information about whether sorting occurs, as demonstrated by irreproducible cancer-research results. NOTE: the effects of this documentation cross application domains, and thus it is likely that security-relevant code elsewhere is affected. This issue is not a Python implementation bug, and there are no reports that NMR researchers were specifically relying on library/glob.html. In other words, because the older documentation stated "finds all the pathnames matching a specified pattern according to the rules used by the Unix shell," one might have incorrectly inferred that the sorting that occurs in a Unix shell also occurred for glob.glob. There is a workaround in newer versions of Willoughby nmr-data_compilation-p2.py and nmr-data_compilation-p3.py, which call sort() directly.
CVE-2019-16935 4 Canonical, Debian, Python and 1 more 6 Ubuntu Linux, Debian Linux, Python and 3 more 2024-11-21 6.1 Medium
The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server.
CVE-2019-16865 3 Fedoraproject, Python, Redhat 4 Fedora, Pillow, Enterprise Linux and 1 more 2024-11-21 7.5 High
An issue was discovered in Pillow before 6.2.0. When reading specially crafted invalid image files, the library can either allocate very large amounts of memory or take an extremely long period of time to process the image.
CVE-2019-16056 7 Canonical, Debian, Fedoraproject and 4 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2024-11-21 7.5 High
An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied. An attack may be the same as in CVE-2019-11340; however, this CVE applies to Python more generally.
CVE-2019-15903 3 Libexpat Project, Python, Redhat 5 Libexpat, Python, Enterprise Linux and 2 more 2024-11-21 7.5 High
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
CVE-2019-13404 2 Microsoft, Python 2 Windows, Python 2024-11-21 N/A
The MSI installer for Python through 2.7.16 on Windows defaults to the C:\Python27 directory, which makes it easier for local users to deploy Trojan horse code. (This also affects old 3.x releases before 3.5.) NOTE: the vendor's position is that it is the user's responsibility to ensure C:\Python27 access control or choose a different directory, because backwards compatibility requires that C:\Python27 remain the default for 2.7.x
CVE-2019-12900 7 Bzip, Canonical, Debian and 4 more 8 Bzip2, Ubuntu Linux, Debian Linux and 5 more 2024-11-21 9.8 Critical
BZ2_decompress in decompress.c in bzip2 through 1.0.6 has an out-of-bounds write when there are many selectors.
CVE-2019-12761 1 Python 1 Pyxdg 2024-11-21 N/A
A code injection issue was discovered in PyXDG before 0.26 via crafted Python code in a Category element of a Menu XML document in a .menu file. XDG_CONFIG_DIRS must be set up to trigger xdg.Menu.parse parsing within the directory containing this file. This is due to a lack of sanitization in xdg/Menu.py before an eval call.
CVE-2019-11324 3 Canonical, Python, Redhat 4 Ubuntu Linux, Urllib3, Enterprise Linux and 1 more 2024-11-21 N/A
The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument.
CVE-2019-11236 2 Python, Redhat 4 Urllib3, Ansible Tower, Enterprise Linux and 1 more 2024-11-21 N/A
In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.
CVE-2019-10160 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2024-11-21 9.8 Critical
A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.
CVE-2019-10138 2 Python, Redhat 2 Novajoin, Openstack 2024-11-21 8.8 High
A flaw was discovered in the python-novajoin plugin, all versions up to, excluding 1.1.1, for Red Hat OpenStack Platform. The novajoin API lacked sufficient access control, allowing any keystone authenticated user to generate FreeIPA tokens.
CVE-2018-25091 2 Python, Redhat 2 Urllib3, Enterprise Linux 2024-11-21 6.1 Medium
urllib3 before 1.24.2 does not remove the authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the authorization header to be exposed to unintended hosts or transmitted in cleartext. NOTE: this issue exists because of an incomplete fix for CVE-2018-20060 (which was case-sensitive).
CVE-2018-25032 11 Apple, Azul, Debian and 8 more 45 Mac Os X, Macos, Zulu and 42 more 2024-11-21 7.5 High
zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
CVE-2018-20852 2 Python, Redhat 4 Python, Ansible Tower, Enterprise Linux and 1 more 2024-11-21 N/A
http.cookiejar.DefaultPolicy.domain_return_ok in Lib/http/cookiejar.py in Python before 3.7.3 does not correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix (e.g., pythonicexample.com to steal cookies for example.com). When a program uses http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing cookies can be leaked to the attacker. This affects 2.x through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7, 3.6.x before 3.6.9, and 3.7.x before 3.7.3.
