Adobe Systems Inc. today issued software updates to fix at least two security vulnerabilities in its widely-used Acrobat and PDF Reader products. Updates are available for Windows, Mac and UNIX versions of these programs.
Acrobat and Reader users can update to the latest version, v. 9.3.4, using the built-in updater, by clicking “Help” and then “Check for Updates.”
Today’s update is an out-of-cycle release for Adobe, which recently moved to a quarterly patch release schedule. The company said the update addresses a vulnerability that was demonstrated at the Black Hat security conference in Las Vegas last month. The release notes also reference a flaw detailed by researcher Didier Stevens back in March. Adobe said it is not aware of any active attacks that are exploiting either of these bugs.
More information on these patches, such as updating older versions of Acrobat and Reader, is available in the Adobe security advisory.
