Adobe warns about PDF software vulnerabilities
Adobe Systems has acknowledged that all versions of its Acrobat and Adobe Reader, creators and readers of the popular PDF document format, contain two critical vulnerabilities.
The company issued a security advisory on its web site, in which it said the first vulnerability “would cause the application to crash and could potentially allow an attacker to take control of the affected system”. This is known to affect the software across all the platforms, including Windows, Mac and Unix.
The second vulnerability, according to the advisory, appears to affect Adobe Reader for Unix only.
The vulnerabilities are known to affect the applications’ JavaScript functions.
Proof-of-concept attack code for both bugs has already been published on the Web.
Stressing that there is no exploit of the vulnerabilities, Adobe says in the statement that it will patch all the affected application. A timetable for the fixes is not yet available.
In the meantime, Adobe recommends its user to disable the JavaScript to mitigate the risk.
Some security experts have urged users to switch PDF viewers while waiting for the patch.
