many packages need to be upgraded

[Patrick Hsieh <pahud@ezplay.tv>]

Hello list,

I've been sticking to woody for a long time. Today I noticed there are some 
packages need to be upgraded:

The following packages will be upgraded
  cpp-2.95 g++-2.95 gcc-2.95 libgd1 libstdc++2.10-dev libstdc++2.10-glibc2.2
  php4 php4-cgi php4-curl php4-imap php4-ldap php4-mysql php4-pear 
13 packages upgraded, 0 newly installed, 0 to remove and 1  not upgraded.
Need to get 4868kB of archives. After unpacking 20.5kB will be used.
Do you want to continue? [Y/n] 


Is there any security issues about these packages or whatever? Basically the 
stable release will not upgrade its packages unless there is security concern 
or big problem. Can someone explain this?
