Title: Borland InterBase Malformed Packet Remote Stack Based Buffer Overflow Vulnerability

Severity: CRITICAL

Description:

Borland InterBase is a scalable database application available for multiple operating platforms.

The application is prone to a remote stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Specifically, an integer overflow occurs when the 'ibserve.exe' database service (bound to TCP port 3050) processes malformed packets.

Attackers can exploit this issue to execute arbitrary code in the context of the application. Failed attacks will likely cause denial-of-service conditions.

Please note that if the application runs as a Windows service, successful attacks will allow arbitrary code to run with SYSTEM-level privileges. This will lead to a complete compromise of an affected computer.

The issue affects Borland InterBase 2007 SP2; other versions may also be vulnerable.

Affected Products:

  • Borland Interbase 2007 SP2
