Detailsinfo

A vulnerability was found in PostgreSQL (Database Software). It has been declared as critical. Affected by this vulnerability is the function make_fetch_stmt of the component fetch. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in gram.y for PostgreSQL 8.0.1 and earlier may allow attackers to execute arbitrary code via (1) a large number of variables in a SQL statement being handled by the read_sql_construct function, (2) a large number of INTO variables in a SELECT statement being handled by the make_select_stmt function, (3) a large number of arbitrary variables in a SELECT statement being handled by the make_select_stmt function, and (4) a large number of INTO variables in a FETCH statement being handled by the make_fetch_stmt function, a different set of vulnerabilities than CVE-2005-0245.

The weakness was released 05/02/2005 (Website). The advisory is shared at archives.postgresql.org. This vulnerability is known as CVE-2005-0247 since 02/08/2005. The exploitation appears to be easy. The attack can be launched remotely. The successful exploitation needs a single authentication. Technical details and also a public exploit are known.

A public exploit has been developed in ANSI C. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 18973 (FreeBSD : postgresql -- multiple buffer overflows in PL/PgSQL parser (6b4b0b3f-8127-11d9-a9e7-0001020eed82)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 19147 (PostgreSQL Multiple Remote Vulnerabilities).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (19378), Tenable (18973), SecurityFocus (BID 12417†), OSVDB (13894†) and Vulnerability Center (SBV-7674†). Entries connected to this vulnerability are available at VDB-23909, VDB-24360 and VDB-24359. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
