Title
ALAS-2016-724 -- обновление безопасности для python26,python27,python34
Description
It was found that Python's httplib library (used urllib, urllib2 and others) did not properly check HTTP header input in HTTPConnection.putheader(). An attacker could use this flow to inject additional headers in a Python application that allows user provided header name or values. (CVE-2016-5699)
It was found that Python's smtplib library did not return an exception if StartTLS fails to establish correctly in the SMTP.starttls() function. An attacker with ability to launch an active man in the middle attack could strip out the STARTTLS command without generating an exception on the python SMTP client application, preventing the establishment of the TLS layer. (CVE-2016-0772)
A vulnerability was discovered in Python, in the built-in zipimporter. A specially crafted zip file placed in a module path such that it would be loaded by a later "import" statement could cause a heap overflow, leading to arbitrary code execution. (CVE-2016-5636)

Comment
: CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython (aka Python) before 2.7.10 and 3.x before 3.4.4 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL.

Comment
: Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow.

Comment
: The smtplib library in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."
