Odd Debian updates appearing

[Fraser Campbell <fraser@georgetown.wehave.net>]

Hi,

I have a number of Debian updates appearing that come from stable as 
opposed to security, this is confusing:

Get:1 http://ftp.us.debian.org sarge/main gzip 1.3.5-10sarge1 [70.8kB]
Get:2 http://ftp.us.debian.org sarge/main vim 1:6.3-071+1sarge1 [707kB]
Get:3 http://ftp.us.debian.org sarge/main vim-common 1:6.3-071+1sarge1 
[3425kB]
Get:4 http://ftp.us.debian.org sarge/main libfam0c102 2.7.0-6sarge1 [25.6kB]
Get:5 http://ftp.us.debian.org sarge/main squirrelmail 2:1.4.4-7 [570kB]

Does anyone know why the above updates appear to be coming from stable? 
 I cannot find recent security annoucements for any of the above packages.

A 6th update was to kernel-image-2.6.8-2-686 (release 2.6.8-16sarge1), I 
found a security announcement for this with a matching md5sum so I 
wasn't too concerned about the kernel update.


Thanks,
Fraser
