Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2019-16935)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing the server_title field in the XML-RPC server (Lib/DocXMLRPCServer.py) in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


2) Untrusted search path (CVE-ID: CVE-2022-26488)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to the search path being inadequately secured. A non-administrative user can trigger a repair that incorrectly adds user-writable paths into PATH, enabling search-path hijacking of other users and system services.


3) Integer overflow (CVE-ID: CVE-2018-20406)

The vulnerability allows a remote attacker to perform denial of service (DoS) attack.

The vulnerability exists due to integer overflow in modules/_pickle.c when processing a large LONG_BINPUT value during the "resize to twice the size" attempt. A remote attacker can supply overly large data, trigger integer overflow and exhaust all resources on the system.


4) Information disclosure (CVE-ID: CVE-2018-20852)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the "http.cookiejar.DefaultPolicy.domain_return_ok" in the "Lib/http/cookiejar.py" file returns incorrect results during cookie domain checks. A remote attacker can trick a victim to execute a program that uses the "http.cookiejar.DefaultPolicy" to make an HTTP connection to an attacker-controlled server with a hostname that has another valid hostname as a suffix.

Successful exploitation of this vulnerability can allow an attacker to gain unauthorized access to sensitive information on the system, such as existing cookies.

5) CRLF injection (CVE-ID: CVE-2019-9947)

The vulnerability allows a remote attacker to perform CRLF injection attacks.

The vulnerability exists within urllib2 implementation for Python 2.x and urllib3 implementation for Python 3.x when processing the path component of a URL that lacks the "?" character within the urllib.request.urlopen() call. A remote attacker with ability to control URL, passed to the application, can use CRLF sequences to split the HTTP request and inject arbitrary HTTP headers into request, made by the application.


6) CRLF injection (CVE-ID: CVE-2019-9740)

The vulnerability allows a remote attacker to perform CRLF injection attacks.

The vulnerability exists within urllib2 implementation for Python 2.x and urllib3 implementation for Python 3.x when processing the path component of a URL after the "?" character within the urllib.request.urlopen() call. A remote attacker with ability to control URL, passed to the application, can use CRLF sequences to split the HTTP request and inject arbitrary HTTP headers into request, made by the application.


7) Input validation error (CVE-ID: CVE-2019-9636)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied input when processing data in Unicode encoding with an incorrect netloc during NFKC normalization. A remote attacker can gain access to sensitive information.


8) CRLF injection (CVE-ID: CVE-2019-18348)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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 (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.)


9) Resource management error (CVE-ID: CVE-2020-8492)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation in urllib.request.AbstractBasicAuthHandler when processing HTTP responses. A remote attacker who controls a HTTP server can send a specially crafted HTTP response to the client application and conduct Regular Expression Denial of Service (ReDoS) attack.


10) Insecure DLL loading (CVE-ID: CVE-2020-15523)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to the "python3X.dll" may use an invalid search path for python3.dll loading (after Py_SetPath has been used). A remote attacker can place a specially crafted Trojan horse python3.dll file, trick the victim into opening a file, associated with the vulnerable application, and execute arbitrary code on victim's system.


11) CRLF injection (CVE-ID: CVE-2020-26116)

The vulnerability allows a remote attacker to inject arbitrary data in server response.

The vulnerability exists due to insufficient validation of attacker-supplied data in "http.client". A remote attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.


12) Code Injection (CVE-ID: CVE-2020-27619)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to Python executed eval() function on the code, retrieved via HTTP protocol in Lib/test/multibytecodec_support.py CJK codec tests. A remote attacker with ability to intercept network traffic can perform a Man-in-the-Middle (MitM) attack and execute arbitrary Python code on the system.


13) Buffer overflow (CVE-ID: CVE-2021-3177)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary within the PyCArg_repr in _ctypes/callproc.c. A remote attacker can pass specially crafted input to the Python applications that accept floating-point numbers as untrusted input, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
