Description Josh Bressers 2005-07-28 16:46:09 EDT
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 16:58:01 EDT
It is built against the system zlib unless Something Is Wrong...

- use system zlib

[root@pepsi ~]# ldd
        libz.so.1 => /usr/lib/libz.so.1 (0x007c1000)
        libc.so.6 => /lib/tls/libc.so.6 (0x003e6000)
        /lib/ld-linux.so.2 (0x009f6000)
Comment 2 Josh Bressers 2005-07-28 17:05:22 EDT
Yes, you are right.  I hadn't checked this myself.  mjc ran a tool over FC4 and
this one popped up.
