Debian DLA-522-1 : python2.7 security update
critical Nessus Plugin ID 91733
Language:
Synopsis
The remote Debian host is missing a security update.Description
- CVE-2016-0772 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-2016-5636 Issue #26171: Fix possible integer overflow and heap corruption in zipimporter.get_data().
- CVE-2016-5699 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).
For Debian 7 'Wheezy', these problems have been fixed in version 2.7.3-6+deb7u3.
We recommend that you upgrade your python2.7 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
