Alpine: python2-tkinter: security update to 2.7.17-r0

critical Tenable Cloud Security Plugin ID 406746

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding
(with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials,
cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit,
urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate
cookies or authentication data and send that information to a different host than when parsed correctly.
This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, 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;
v3.7.3, v3.7.3rc1, 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-2019-9636)

- 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. (CVE-2019-9948)

- 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-2019-15903)

- 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)

- 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-2019-16935)
