New Firebird packages fix several vulnerabilities in debian

This Debian security advisory is a bit unusual. While it’s normally
our strict policy to backport security bugfixes to older releases, this
turned out to be infeasible for Firebird 1.5 due to large infrastructural
changes necessary to fix these issues. As a consequence security support
for Firebird 1.5 is hereby discontinued, leaving two options to
administrators running a Firebird database:

Firebird Relational Database ‘protocol.cpp’ XDR Protocol Remote Memory Corruption Vulnerability

Firebird is prone to an integer-overflow vulnerability because it fails to ensure that integer values aren’t overrun. Attackers may exploit this issue to overflow a buffer and to corrupt process memory.

Attackers may be able to execute arbitrary machine code in the context of an affected application. Failed exploit attempts will likely result in a denial-of-service condition.

Oops, Look At That Phoenix, Rising From The Ashes

In a story headlined, “Open Source Code Contains Security Holes,” I referred recently to the Firebird database project as “somewhat moribund.” So imagine my surprise when a reader pointed out it was named project of the month in December by SourceForge, the dominant host of open source projects. Geez. Then there was the case of the supposedly “inactive” FreeBSD Unix.

Firebird is alive and secure

The following was sent to Charles Babcock at Information week in reply to an article entitled:

Open Source Code Contains Security Holes

As a developer and administrator of the Firebird Project I completely reject the statement you made in the above article.

“The somewhat moribund Firebird project, for example, is listed with 195 identified defects, of which it has verified zero and fixed zero. The active Firefox browser project, on the other hand,
has fixed 370 bugs, verified 56 and faces another 246 to verify and fix.”
