Subject: [USN-1126-1] PHP vulnerabilities
==========================================================================
Ubuntu Security Notice USN-1126-1
April 29, 2011
php5 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 9.10
- Ubuntu 8.04 LTS
- Ubuntu 6.06 LTS
Summary:
Multiple vulnerabilities in PHP.
Software Description:
- php5: HTML-embedded scripting language interpreter
Details:
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)
