Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Heap-based buffer underflow (CVE-ID: CVE-2012-2688)

The vulnerability allows a remote attacker to cause DoS conditions or execute arbitrary code on the target system.

The weakness exists due to heap-based buffer underflow in the PHP scandir() function. A remote attacker can create specially crafted files, upload them to a directory the scandir() function runs on and cause the PHP interpreter to crash or execute arbitrary code with privileges of the web server.

Successful exploitation of the vulnerability results in denial of service or arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-3365)

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

The SQLite functionality in PHP before 5.3.15 allows remote attackers to bypass the open_basedir protection mechanism via unspecified vectors.


3) Input validation error (CVE-ID: CVE-2012-3450)

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

pdo_sql_parser.re in the PDO extension in PHP before 5.3.14 and 5.4.x before 5.4.4 does not properly determine the end of the query string during parsing of prepared statements, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted parameter value.
