Ubuntu Security Notice USN-973-1 August 17, 2010
koffice vulnerabilities
CVE-2009-0146, CVE-2009-0147, CVE-2009-0165, CVE-2009-0166,
CVE-2009-0195, CVE-2009-0799, CVE-2009-0800, CVE-2009-1179,
CVE-2009-1180, CVE-2009-1181, CVE-2009-3606, CVE-2009-3608,
CVE-2009-3609
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 9.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 9.04:
kword 1:1.6.3-7ubuntu6.1

In general, a standard system update will make all the necessary changes.

Details follow:

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.

After a standard system update you need to restart your session to make
all the necessary changes.

Details follow:

It was discovered that FreeType did not correctly handle certain malformed
font files. If a user were tricked into using a specially crafted font
file, a remote attacker could cause FreeType to crash or possibly execute
arbitrary code with user privileges.

A security issue affects the following Ubuntu releases:

Ubuntu 9.04
Ubuntu 9.10
Ubuntu 10.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the

Details follow:

It was discovered that GPGSM in GnuPG2 did not correctly handle
certificates with a large number of Subject Alternate Names. If a user or
automated system were tricked into processing a specially crafted
certificate, an attacker could cause a denial of service or execute
arbitrary code with privileges of the user invoking the program.

===========================================================

Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas
Salomäki discovered that the slap_modrdn2mods function in modrdn.c

smr_normalize function. A remote attacker could use specially crafted
modrdn requests to crash the slapd daemon or possibly execute arbitrary
code. (CVE-2010-0211)

Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas
Salomäki discovered that OpenLDAP does not properly handle empty
RDN strings. A remote attacker could use specially crafted modrdn
requests to crash the slapd daemon. (CVE-2010-0212)

Details follow:

Junjiro R. Okajima discovered that knfsd did not correctly handle
strict overcommit. A local attacker could exploit this to crash knfsd,
leading to a denial of service. (Only Ubuntu 6.06 LTS and 8.04 LTS were
affected.) (CVE-2008-7256, CVE-2010-1643)

Chris Guo, Jukka Taimisto, and Olli Jarva discovered that SCTP did
not correctly handle invalid parameters. A remote attacker could send
specially crafted traffic that could crash the system, leading to a
denial of service. (CVE-2010-1173)

non-executable stacks. This made userspace applications vulnerable to
exploits that would have been otherwise blocked due to non-executable
memory protections. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1451)

Dan Rosenberg discovered that the btrfs clone function did not correctly
validate permissions. A local attacker could exploit this to read
sensitive information, leading to a loss of privacy. (Only Ubuntu 9.10
was affected.) (CVE-2010-1636)

Dan Rosenberg discovered that GFS2 set_flags function did not correctly
validate permissions. A local attacker could exploit this to gain
access to files, leading to a loss of privacy and potential privilege
escalation. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-1641)

Shi Weihua discovered that btrfs xattr_set_acl function did not
correctly validate permissions. A local attacker could exploit
this to gain access to files, leading to a loss of privacy and
potential privilege escalation. (Only Ubuntu 9.10 and 10.04 LTS were
affected.) (CVE-2010-2071)

Andre Osterhues discovered that eCryptfs did not correctly calculate
hash values. A local attacker with certain uids could exploit this to
crash the system or potentially gain root privileges. (Ubuntu 6.06 LTS
was not affected.) (CVE-2010-2492)

https://launchpad.net/bugs/610300
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 10.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 10.04 LTS:
likewise-open 5.4.0.42111-2ubuntu1.2

In general, a standard system update will make all the necessary changes.

Details follow:

USN-964-1 fixed vulnerabilities in Likewise Open. The upstream fixes
were incomplete, which caused problems running certain services. This
update fixes the problem.

We apologize for the inconvenience.
