Security firm Security Explorations released information pertaining to a new Java exploit on Tuesday that affects all of the currently supported versions of the software on all platforms, including Java 5, Java 6 and Java 7. The zero-day vulnerability is considered critical and approximately 1 billion PC and Mac computers could be at risk. Adam Gowdiak, the firm’s CEO, notes that his company has not discovered an active attack that exploits the vulnerability, however. Oracle (ORCL) is aware of the issue and, according to ComputerWorld, the bug will be patched in a future Java security update. The latest exploit follows a string of vulnerabilities that have been discovered in the Java software over the past year.
