Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2012-2386)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Integer overflow in the phar_parse_tarfile function in tar.c in the phar extension in PHP before 5.3.14 and 5.4.x before 5.4.4. A remote attacker can use a crafted tar file that triggers a heap-based buffer overflow. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Buffer overflow (CVE-ID: CVE-2012-2329)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Buffer overflow in the apache_request_headers function in sapi/cgi/cgi_main.c in PHP 5.4.x before 5.4.3 allows remote attackers to cause a denial of service (application crash) via a long string in the header of an HTTP request.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-2335)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

php-wrapper.fcgi does not properly handle command-line arguments, which allows remote attackers to bypass a protection mechanism in PHP 5.3.12 and 5.4.2 and execute arbitrary code by leveraging improper interaction between the PHP sapi/cgi/cgi_main.c component and a query string beginning with a +- sequence.


4) Input validation error (CVE-ID: CVE-2012-2336)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

sapi/cgi/cgi_main.c in PHP before 5.3.13 and 5.4.x before 5.4.3, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to cause a denial of service (resource consumption) by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'T' case. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1823.
