Insight
Will Dormann, Alin Rad Pop, Braden Thomas, and Drew Yao discovered that the Xpdf used in KOffice contained multiple security issues in its JBIG2 decoder. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0146, CVE-2009-0147, CVE-2009-0166, CVE-2009-0799, CVE-2009-0800, CVE-2009-1179, CVE-2009-1180, CVE-2009-1181) It was discovered that the Xpdf used in KOffice contained multiple security issues when parsing malformed PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-3606, CVE-2009-3608, CVE-2009-3609) KOffice in Ubuntu 9.04 uses a very old version of Xpdf to import PDFs into KWord. Upstream KDE no longer supports PDF import in KOffice and as a result it was dropped in Ubuntu 9.10. While an attempt was made to fix the above issues, the maintenance burden for supporting this very old version of Xpdf outweighed its utility, and PDF import is now also disabled in Ubuntu 9.04.
