Ubuntu 9.04 : koffice vulnerabilities (USN-973-1)

Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.

Solution :

Update the affected packages.

Risk factor :
