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

high Nessus Plugin ID 55087

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).
