Alpine: python2: security update to 2.7.16-r1

critical Tenable Cloud Security Plugin ID 406737

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)
