Vulnerability in all versions of Ruby on Rails

• A flaw in the implementation of the ‘finder’ method of the Active Record system could allow SQL injection
• If users can supply a symbol keyed hash as the second parameter to the find_by_* method, they would be able to inject arbitrary SQL
• The very popular Authlogic library is vulnerable in some instances, specifically when the attacker knows the HMAC key that is used to sign cookies
• Authlogic stores session data in a cookie on the users’ computer, and this cookie is cryptographically signed with HMAC to ensure it cannot be tampered with. This works well when the HMAC key is secret, but many examples on github and many open source applications include a default HMAC that is often not changed, resulting in a large install base using publically known HMAC keys, allowing them to be exploited
• CVE–2012–5664
• Ruby on Rails recommends upgrading to the latest version in your desired branch: 3.2.10, 3.1.9 or 3.0.18

Zero day exploit for nVidia display drivers in windows

• The nVidia driver service listens on a named pipe (\pipe\nsvr) that has a null access control list
• Any user logged on to the machine or any remote user in a domain context (if the machine has file sharing enabled, and the firewall relaxed/disabled) could have access to the service
• The attacker could then trigger a buffer overflow due to a bad memmove operation
• The exploit could be used to escalate privileges and gain full control over the machine
• The exploit is also able to bypass data execution prevention (DEP) and the address space layout randomization (ASLR) feature introduced in Windows Vista
• The exploit was initially made public because the researcher felt that the risk was minimal, however after some pressure from the community and possibly the discovery of additional attack vectors, the exploit was taken down
