Ubuntu 6.06 LTS / 8.04 LTS / 9.10 / 10.04 LTS / 10.10 / 11.04 : php5 regressions (USN-1126-2)

Ubuntu Security Notice (C) 2011-2014 Canonical, Inc. / NASL script (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN 1126-1 fixed several vulnerabilities in PHP. The fix for
CVE-2010-4697 introduced an incorrect reference counting regression in
the Zend engine that caused the PHP interpreter to segfault. This
regression affects Ubuntu 6.06 LTS and Ubuntu 8.04 LTS.

The fixes for CVE-2011-1072 and CVE-2011-1144 introduced a regression
in the PEAR installer that prevented it from creating its cache
directory and reporting errors correctly.

We apologize for the inconvenience.

Stephane Chazelas discovered that the /etc/cron.d/php5 cron job for
PHP 5.3.5 allows local users to delete arbitrary files via a symlink
attack on a directory under /var/lib/php5/. (CVE-2011-0441)

Raphael Geisert and Dan Rosenberg discovered that the PEAR
installer allows local users to overwrite arbitrary files
via a symlink attack on the package.xml file, related to the
(1) download_dir, (2) cache_dir, (3) tmp_dir, and (4)
pear-build-download directories. (CVE-2011-1072,
CVE-2011-1144)

Ben Schmidt discovered that a use-after-free vulnerability
in the PHP Zend engine could allow an attacker to cause a
denial of service (heap memory corruption) or possibly
execute arbitrary code. (CVE-2010-4697)

Martin Barbella discovered a buffer overflow in the PHP GD
extension that allows an attacker to cause a denial of
service (application crash) via a large number of anti-
aliasing steps in an argument to the imagepstext function.
(CVE-2010-4698)

It was discovered that PHP accepts the \0 character in a
pathname, which might allow an attacker to bypass intended
access restrictions by placing a safe file extension after
this character. This issue is addressed in Ubuntu 10.04 LTS,
Ubuntu 10.10, and Ubuntu 11.04. (CVE-2006-7243)

Maksymilian Arciemowicz discovered that the grapheme_extract
function in the PHP Internationalization extension (Intl)
for ICU allow an attacker to cause a denial of service
(crash) via an invalid size argument, which triggers a NULL
pointer dereference. This issue affected Ubuntu 10.04 LTS,
Ubuntu 10.10, and Ubuntu 11.04. (CVE-2011-0420)

Maksymilian Arciemowicz discovered that the _zip_name_locate
function in the PHP Zip extension does not properly handle a
ZIPARCHIVE::FL_UNCHANGED argument, which might allow an
attacker to cause a denial of service (NULL pointer
dereference) via an empty ZIP archive. This issue affected
Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, Ubuntu
10.10, and Ubuntu 11.04. (CVE-2011-0421)

Luca Carettoni discovered that the PHP Exif extension
performs an incorrect cast on 64bit platforms, which allows
a remote attacker to cause a denial of service (application
crash) via an image with a crafted Image File Directory
(IFD). (CVE-2011-0708)

Jose Carlos Norte discovered that an integer overflow in the
PHP shmop extension could allow an attacker to cause a
denial of service (crash) and possibly read sensitive memory
function. (CVE-2011-1092)

Felipe Pena discovered that a use-after-free vulnerability
in the substr_replace function allows an attacker to cause a
denial of service (memory corruption) or possibly execute
arbitrary code. (CVE-2011-1148)

Felipe Pena discovered multiple format string
vulnerabilities in the PHP phar extension. These could allow
an attacker to obtain sensitive information from process
memory, cause a denial of service (memory corruption), or
possibly execute arbitrary code. This issue affected Ubuntu
10.04 LTS, Ubuntu 10.10, and Ubuntu 11.04.(CVE-2011-1153)

It was discovered that a buffer overflow occurs in the
strval function when the precision configuration option has
a large value. The default compiler options for Ubuntu 8.04
LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, Ubuntu 10.10, and Ubuntu
11.04 should reduce the vulnerability to a denial of
service. (CVE-2011-1464)

It was discovered that an integer overflow in the
SdnToJulian function in the PHP Calendar extension could
allow an attacker to cause a denial of service (application
crash). (CVE-2011-1466)

Tomas Hoger discovered that an integer overflow in the
NumberFormatter::setSymbol function in the PHP Intl
extension could allow an attacker to cause a denial of
service (application crash). This issue affected Ubuntu
10.04 LTS, Ubuntu 10.10, and Ubuntu 11.04. (CVE-2011-1467)

It was discovered that multiple memory leaks in the PHP
OpenSSL extension might allow a remote attacker to cause a
denial of service (memory consumption). This issue affected
Ubuntu 10.04 LTS, Ubuntu 10.10, and Ubuntu 11.04.
(CVE-2011-1468)

Daniel Buschke discovered that the PHP Streams component in
PHP handled types improperly, possibly allowing an attacker
to cause a denial of service (application crash).
(CVE-2011-1469)

It was discovered that the PHP Zip extension could allow an
attacker to cause a denial of service (application crash)
via a ziparchive stream that is not properly handled by the
stream_get_contents function. This issue affected Ubuntu
8.04 LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, Ubuntu 10.10, and
Ubuntu 11.04. (CVE-2011-1470)

It was discovered that an integer signedness error in the
PHP Zip extension could allow an attacker to cause a denial
of service (CPU consumption) via a malformed archive file.
This issue affected Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu
10.04 LTS, Ubuntu 10.10, and Ubuntu 11.04. (CVE-2011-1470)
(CVE-2011-1471).
