Python is an interpreted, interactive, object-oriented programming language that supports modules, classes, exceptions, high-level dynamic data types, and dynamic typing. The python27 packages provide a stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and PostgreSQL.

The following packages have been upgraded to a later upstream version: python2 (2.7.17). (BZ#1759944)

Security Fix(es):

* python-urllib3: Cross-host redirect does not remove Authorization header allow for credential exposure (CVE-2018-20060)

* python: Cookie domain check returns incorrect results (CVE-2018-20852)

* python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236)

* python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324)

* python: email.utils.parseaddr wrongly parses email addresses (CVE-2019-16056)

* python-requests: Redirect from HTTPS to HTTP does not remove Authorization header (CVE-2018-18074)

Affected: CleanStart: python3

Multiple security vulnerabilities affect the python3 package. These issues are resolved in later releases. See references for individual vulnerability details.

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.

expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees run-mailcap in the Debian mime-support package before 3.52-1+deb7u1 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename. In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start o…
