Adobe has issued a second fix for a vulnerability in Acrobat and Reader versions 7 and 8 for Mac OS X and Windows operating systems.
The update patches a vulnerability in the handling of PDF files which, if exploited, could allow an attacker to remotely execute code on a targeted machine. Adobe first warned of the flaw late last month.
The company issued an update last week for version 9 of both Reader and Acrobat, the first official patches to be released. Two weeks earlier, a security researcher had crafted a home-made patch to address the flaw.
The update nearly completes patching for the flaw, which has been the target of limited attacks since its discovery. Adobe is hoping to issue a fix for Unix versions of Reader and Acrobat by next Tuesday.
