A vulnerability, which was classified as very critical, has been found in Firebird SQL Server 2.0.0.12748/2.0.1.12855 (Database Software). This issue affects the function isc_attach_database. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple stack-based buffer overflows in Firebird LI 2.0.0.12748 and 2.0.1.12855, and WI 2.0.0.12748 and 2.0.1.12855, allow remote attackers to execute arbitrary code via (1) a long attach request on TCP port 3050 to the isc_attach_database function or (2) a long create request on TCP port 3050 to the isc_create_database function.

The bug was discovered 10/03/2007. The weakness was disclosed 10/06/2007 by Adriano Lima with RISE Security (Website). It is possible to read the advisory at vupen.com.
