Sorry but the spec file has "BuildRequires: zlib-devel" so it is used
for building and, if I understand correctly, the CVE effectively means
ClamAV needs to be rebuilt against the fixed zlib/zlib-devel. Please
let
me know if I have misunderstood.
That means it is using the OS zlib to build things. If RHEL does not
ship any update, then rebuilding it won't fix anything.
If you backport the fix to the shipped zlib source code and build it
yourself, then if all goes well everything which was built against the
original ABI will continue to work without recompiling
If you compile a new zlib then you may need to recompile it but also
every other spec that requires zlib-devel.
That is going too far for me. I guess I am stuck on RedHat. I have
compiled 0.103.7-2 but with the current zlib/zlib-devel.
