Detailsinfo

A vulnerability was found in PostgreSQL (Database Software) and classified as critical. This issue affects the function refcursor. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in gram.y for PostgreSQL 8.0.0 and earlier may allow attackers to execute arbitrary code via a large number of arguments to a refcursor function (gram.y), which leads to a heap-based buffer overflow, a different vulnerability than CVE-2005-0247.

The bug was discovered 02/01/2005. The weakness was shared 02/01/2005 (Website). The advisory is shared at xforce.iss.net. The identification of this vulnerability is CVE-2005-0245 since 02/08/2005. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is available at securityfocus.com. It is declared as proof-of-concept.
