Adobe on Wednesday released an updated version of its Photoshop CS4 software to remedy a number of "critical" vulnerabilities that could permit attackers to take control of targeted systems, according to an advisory. Users can be infected if they are tricked into opening a malicious .ASL, .ABR or .GRD file. Adobe encourages customers to upgrade to version 11.0.2. None of the flaws corrected are present in Photoshop CS5. — DK
