Description Moritz Muehlenhoff univentionstaff 2014-11-24 15:51:25 CET
Denial of service in various stdlib modules when connecting to a malicious server (CVE-2013-1752, CVE-2013-1753)
Incorrect handling of URL-encoded path separators in URLs in the CGIHTTPServer module (CVE-2014-4650)
Integer overflow in the buffer() function (CVE-2014-7185)
Memory disclosure in the _json module (CVE-2014-4616)
Comment 1 Moritz Muehlenhoff univentionstaff 2014-12-15 10:05:34 CET
CVE-2014-9365: Python 2.7.9 and 3.4.3 now validate SSL certificates in httplib, urllib, urllib2 and xmlrpclib. Formerly, the hostname wasn't matched against the remote host and there was no trust store checked by default. This will not be backported to earlier 2.x releases by upstream.
Comment 2 Arvid Requate univentionstaff 2015-05-06 22:10:52 CEST
All of the six issues above have been classified as "Minor issue" in Debian.
Comment 3 Stefan Gohmann univentionstaff 2015-09-01 14:19:14 CEST
Only minor issue(s). Removing target milestone.
Comment 4 Arvid Requate univentionstaff 2016-06-27 12:40:19 CEST
Upstream Debian package version 2.7.3-6+deb7u3 fixes these issues:

* A vulnerability in smtplib allowing MITM attacker to perform a startTLS stripping attack. smtplib does not seem to raise an exception when the remote end (smtp server) is capable of negotiating starttls but fails to respond with 220 (ok) to an explicit call of SMTP.starttls(). This may allow a malicious MITM to perform a startTLS stripping attack if the client code does not explicitly check the response code for startTLS (CVE-2016-0772)

* Issue #26171: Fix possible integer overflow and heap corruption in zipimporter.get_data() (CVE-2016-5636)

* Protocol injection can occur not only if an application sets a header based on user-supplied values, but also if the application ever tries to fetch a URL specified by an attacker (SSRF case) OR if the application ever accesses any malicious web server (redirection case) (CVE-2016-5699)
Comment 5 Janek Walkenhorst univentionstaff 2016-08-26 15:33:29 CEST
Tests (i386): OK
Advisory: python2.7.yaml
Comment 6 Arvid Requate univentionstaff 2016-09-05 18:57:59 CEST
Verified:
* 2.7.3-6+deb7u3 imported and built
* No UCS 4.1 patches
* Package update Ok (amd64)
* Advisory Ok
