Firebird “fbserver” Service Connect Request Handling Buffer Overflow Vulnerability

Vulnerability has been identified in Firebird, which could be exploited by remote attackers to cause a denial of service or take complete control of an affected system. This issue is caused by a buffer overflow error in the “fbserver.exe” service (port 3050/TCP) when processing a “connect” request (0x1) with a large “p_cnct_count” value, which could be exploited by remote unauthenticated attackers to crash an affected application or execute arbitrary code with the privileges of the database.

Affected Products

Firebird version 2.0.0

Solution

Upgrade ASAP to Firebird version 2.0.1 :

Talk on database locking and relational – oo bridge

I did a talk on various strategies of how to bridge relational databases and object-oriented programming. In retrospect I should have submitted this as a “double feature” talk, so that I could cover more ground on the actual using of the existing packages in the PHP space.

The other talk was on database locking. I think the biggest eye opener for people in that talk was about how MVCC, found in Firebird, Oracle, InnoDB and PostreSQL, really works and how to control the behavior as needed.
