Important: poppler security update
Security Advisory: Important
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.
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)
