Description
This security bulletin contains information about 1 vulnerability.
1) Data Handling (CVE-ID: CVE-2013-7440)
CWE-ID: CWE-19 - Data Handling
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate.
Remediation
Install update from vendor's website.
