KrebsOnSecurity.com reports Adobe Systems Inc. today issued software updates to fix at least two security vulnerabilities in its widely-used Acrobat and PDF Reader products. 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.”
Krebs writes that "today’s update is an out-of-cycle release for Adobe, which recently moved to a quarterly patch release schedule. ... More information on these patches, such as updating older versions of Acrobat and Reader, is available in the Adobe security advisory."
