详细描述

python-urllib3: Python3 HTTP module with connection pooling and file POST abilities.
cyrus-sasl: The cyrus-sasl package contains the Cyrus implementation of SASL. SASL is the Simple Authentication and Security Layer, a method for adding authentication support to connection-based protocols.

Security Fix(es):
python-urllib3: A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks.(CVE-2022-0391)
python-urllib3: A Cross-site Scripting (XSS) vulnerability was found in the python-lxml's clean module. The module's parser did not properly imitate browsers, causing different behaviors between the sanitizer and the user's page. This flaw allows a remote attacker to run arbitrary HTML/JS code. The highest threat from this vulnerability is to confidentiality and integrity.(CVE-2020-27783)
python-urllib3: In Python3's Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP.(CVE-2020-27619)
python-urllib3: 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-2019-16056)
python-urllib3: A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability.(CVE-2021-3737)
python-urllib3: SQLAlchemy through 1.2.17 and 1.3.x through 1.3.0b2 allows SQL Injection via the order_by parameter.(CVE-2019-7164)
python-urllib3: 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-2019-11324)
python-urllib3: A flaw was found in python-jinja2. The ReDOS vulnerability of the regex is mainly due to the sub-pattern [a-zA-Z0-9._-]+.[a-zA-Z0-9._-]+. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.(CVE-2020-28493)
python-urllib3: A flaw was found in python. A stack-based buffer overflow was discovered in the ctypes module provided within Python. Applications that use ctypes without carefully validating the input passed to it may be vulnerable to this flaw, which would allow an attacker to overflow a buffer on the stack and crash the application. The highest threat from this vulnerability is to system availability.(CVE-2021-3177)
python-urllib3: SQLAlchemy 1.2.17 has SQL Injection when the group_by parameter can be controlled.(CVE-2019-7548)
python-urllib3: A reflected cross-site scripting (XSS) vulnerability was found in Python XML-RPC server. The `server_title` field is not sufficiently sanitized allowing malicious JavaScript to be injected. Successful exploitation would allow a remote attacker to execute JavaScript code within the context of the affected user.(CVE-2019-16935)
python-urllib3: It was discovered that python's functions urllib.parse.urlsplit and urllib.parse.urlparse do not properly handle URLs encoded with Punycode/Internationalizing Domain Names in Applications (IDNA), which may result in a wrong domain name (specifically the netloc component of URL - user@domain:port) being returned by those functions. 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-2019-9636)
python-urllib3: In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.(CVE-2019-11236)
python-urllib3: A flaw was found in python-babel. A path traversal vulnerability was found in how locale data files are checked and loaded within python-babel, allowing a local attacker to trick an application that uses python-babel to load a file outside of the intended locale directory. The highest threat from this vulnerability is to data confidentiality and integrity as well as service availability.(CVE-2021-42771)
python-urllib3: There's a flaw in python-lxml's HTML Cleaner component, which is responsible for sanitizing HTML and Javascript. An attacker who is able to submit a crafted payload to a web service using python-lxml's HTML Cleaner may be able to trigger script execution in clients such as web browsers. This can occur because the HTML Cleaner did not remove scripts within SVG images in data URLs such as . XSS can result in impacts to the integrity and availability of the web page, as well as a potential impact to data confidentiality in some circumstances.(CVE-2021-43818)
python-urllib3: A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.(CVE-2021-4189)
python-urllib3: An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3. 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 path component of a URL that lacks a ? character) followed by an HTTP header or a Redis command. This is similar to the CVE-2019-9740 query string issue. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.(CVE-2019-9947)
python-urllib3: The package python/cpython is vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.(CVE-2021-23336)
python-urllib3: There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability.(CVE-2021-3733)
python-urllib3: ** DISPUTED ** An issue was discovered in NumPy 1.16.0 and earlier. It uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a numpy.load call. NOTE: third parties dispute this issue because it is a behavior that might have legitimate applications in (for example) loading serialized Python object arrays from trusted and authenticated sources.(CVE-2019-6446)
python-urllib3: 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.(CVE-2019-9948)
python-urllib3: A flaw was found in python-babel. A path traversal vulnerability was found in how locale data files are checked and loaded within python-babel, allowing a local attacker to trick an application that uses python-babel to load a file outside of the intended locale directory. The highest threat from this vulnerability is to data confidentiality and integrity as well as service availability.(CVE-2021-20095)
python-urllib3: A flaw was found in python-lxml. The HTML5 formaction attribute is not input sanitized like the HTML action attribute is which can lead to a Cross-Site Scripting attack (XSS) when an application uses python-lxml to sanitize user inputs. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2021-28957)
python-urllib3: bugfix
cyrus-sasl: A flaw was found in the SQL plugin shipped with Cyrus SASL. The vulnerability occurs due to failure to properly escape SQL input and leads to an improper input validation vulnerability. This flaw allows an attacker to execute arbitrary SQL commands and the ability to change the passwords for other accounts allowing escalation of privileges.(CVE-2022-24407)
cyrus-sasl: (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.(CVE-2019-19906)
cyrus-sasl: bugfix
