MS KB2661254: Update For Minimum Certificate Key Length
medium Nessus Plugin ID 62466
Language:
Synopsis
The remote Windows host is configured to trust SSL/TLS certificates with weak keys.Description
The remote host is missing Microsoft KB2661254. This update restricts the use of RSA keys less than 1024 bits in length. Keys of shorter lengths are more susceptible to brute-force attacks, which could allow a man-in-the-middle attacker to intercept and/or modify data encrypted over SSL/TLS.Solution
Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.Please note this update could cause applications or services (e.g., email, signed applications, private PKI) to stop working in some environments. Refer to the Microsoft advisory for more information.
