Description Josh Bressers 2005-07-28 20:46:09 UTC 
perl-Compress-Zlib contains an internal version of the zlib source.  A number of
buffer overflow issues have been recently fixed in zlib.

See bug 163037 and bug 162391 for more information.


Ideally, we should build perl-Compress-Zlib to use the system zlib to avoid
having to rebuild it in the future.
Comment 1 Joe Orton 2005-07-28 20:58:01 UTC 
It is built against the system zlib unless Something Is Wrong...

- use system zlib

Yes, you are right.  I hadn't checked this myself.  mjc ran a tool over FC4 and
this one popped up.
