Adobe Systems on Tuesday warned users of its Adobe Reader 5.0 for Linux and Unix that a security vulnerability could leave their systems open to remote hijacking.
The buffer overflow vulnerability is present in Versions 5.0.9 or 5.0.10 for Linux, Solaris, IBM-AIX and HP-UX, according to the companys security alert. The Denmark-based security analyst company Secunia rated the flaw as “highly critical,” and Adobe advised users to upgrade to more recent versions of Reader.
The Adobe Systems Inc. advisory said the vulnerability could cause a buffer overflow that would enable the remote execution of arbitrary code if the user were to open a PDF document attached to e-mail or accessed via a Web link.
Adobe advises users of earlier versions to download and install Adobe Reader 7.0.
