RHSA-2009:0480: Important: poppler security update

Poppler is a Portable Document Format (PDF) rendering library, used byapplications such as Evince.Multiple integer overflow flaws were found in poppler. An attacker couldcreate a malicious PDF file that would cause applications that use poppler(such as Evince) to crash or, potentially, execute arbitrary code whenopened. (CVE-2009-0147, CVE-2009-1179, CVE-2009-1187, CVE-2009-1188)Multiple buffer overflow flaws were found in poppler's JBIG2 decoder. Anattacker could create a malicious PDF file that would cause applicationsthat use poppler (such as Evince) to crash or, potentially, executearbitrary code when opened. (CVE-2009-0146, CVE-2009-1182)Multiple flaws were found in poppler's JBIG2 decoder that could lead to thefreeing of arbitrary memory. An attacker could create a malicious PDF filethat would cause applications that use poppler (such as Evince) to crashor, potentially, execute arbitrary code when opened. (CVE-2009-0166,CVE-2009-1180)Multiple input validation flaws were found in poppler's JBIG2 decoder. Anattacker could create a malicious PDF file that would cause applicationsthat use poppler (such as Evince) to crash or, potentially, executearbitrary code when opened. (CVE-2009-0800)Multiple denial of service flaws were found in poppler's JBIG2 decoder. Anattacker could create a malicious PDF file that would cause applicationsthat use poppler (such as Evince) to crash when opened.
