Apple has released iOS 7 for the iPhone 4 and later, iPod touch 5th generation and later, and iPad 2 and later to address multiple vulnerabilities. These vulnerabilities could allow remote attackers to execute arbitrary code, cause a cross-site scripting attack, bypass security restrictions, or cause a denial-of-service condition.
US-CERT encourages users and administrators to review Apple Support Article HT5934 and follow best practice security policies to determine if their organization is affected and the appropriate response.
