CVE-2016-5636 Integer overflow in the get_data function in zipimport.c in CPython allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow. CVE-2016-5699 CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL. CVE-2018-20406 Modules/_pickle.c has an integer overflow via a large LONG_BINPUT value that is mishandled during a "resize to twice the size" attempt. This issue might cause memory exhaustion, but is only relevant if the pickle format is used for serializing tens or hundreds of gigabytes of data. CVE-2019-5010 NULL pointer dereference using a specially crafted X509 certificate. For Debian 8 "Jessie", these problems have been fixed in version 3.4.2-1+deb8u2.
