RHSA-2009:0480 - Security Advisory

Topic

Updated poppler packages that fix multiple security issues 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.

Description

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-2009-0147, CVE-2009-1179, CVE-2009-1187, CVE-2009-1188)

Multiple buffer overflow flaws were found in poppler's JBIG2 decoder. 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-2009-0146, CVE-2009-1182)

Multiple flaws were found in poppler's JBIG2 decoder that could lead to the
freeing of arbitrary memory. 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-2009-0166,
CVE-2009-1180)

Multiple input validation flaws were found in poppler's JBIG2 decoder. 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-2009-0800)

Multiple denial of service flaws were found in poppler's JBIG2 decoder. An
attacker could create a malicious PDF file that would cause applications
that use poppler (such as Evince) to crash when opened. (CVE-2009-0799,
CVE-2009-1181, CVE-2009-1183)

Red Hat would like to thank Braden Thomas and Drew Yao of the Apple Product
Security team, and Will Dormann of the CERT/CC for responsibly reporting
these flaws.

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