Important: poppler security and bug fix update

Updated poppler packages that fix multiple security issues and a bug are
now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Poppler is a Portable Document Format (PDF) rendering library, used by
applications such as Evince.

Multiple integer overflow flaws were found in poppler. An attacker could
create a malicious PDF file that would cause applications that use poppler
(such as Evince) to crash or, potentially, execute arbitrary code when
opened. (CVE-2009-3603, CVE-2009-3608, CVE-2009-3609)

Red Hat would like to thank Chris Rohlf for reporting the CVE-2009-3608
issue.

This update also corrects a regression introduced in the previous poppler
security update, RHSA-2009:0480, that prevented poppler from rendering
certain PDF documents correctly. (BZ#528147)

Users are advised to upgrade to these updated packages, which contain
backported patches to resolve these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
