The remote Red Hat host is missing one or more security updates.
Updated acroread packages that fix multiple security issues and three
bugs are now available for Red Hat Enterprise Linux 5 Supplementary.
This update has been rated as having critical security impact by the
Red Hat Security Response Team.
Adobe Reader allows users to view and print documents in Portable
Document Format (PDF).
This update fixes several vulnerabilities in Adobe Reader. These
vulnerabilities are summarized on the Adobe Security Advisory
APSB10-02 page listed in the References section. A specially crafted
PDF file could cause Adobe Reader to crash or, potentially, execute
arbitrary code as the user running Adobe Reader when opened.
(CVE-2009-4324, CVE-2009-3953, CVE-2009-3954, CVE-2009-3955,
This update also fixes the following bugs :
* the acroread process continued to run even after closing a PDF file.
If multiple PDF files were opened and then closed, the acroread
processes continued to run and consume system resources (up to 100%
CPU usage). With this update, the acroread process correctly exits,
which resolves this issue. (BZ#473217)
* the PPKLite.api plug-in was missing, causing Adobe Reader to crash
when attempting to open signed PDF files. For such files, if an
immediate crash was not observed, clicking on the Signature Panel
could trigger one. With this update, the PPKLite.api plug-in is
included, which resolves this issue. (BZ#472975)
* Adobe Reader has been upgraded to version 9.3. (BZ#497957)
Adobe have discontinued support for Adobe Reader 8 for Linux. All
users of Adobe Reader are advised to install these updated packages,
which contain Adobe Reader version 9.3, which is not vulnerable to
these issues and fixes these bugs. All running instances of Adobe
Reader must be restarted for the update to take effect.
