Select your preferable compression library and google for it with +CVE.
E.g. in zlib:
=
http://www.cvedetails.com/vulnerability-list/vendor_id-72/product_id-1820/=
GNU-Zlib.html
=E2=80=A6allows remote attackers to cause a denial of service (crash) =
via a crafted compressed stream=E2=80=A6
=E2=80=A6allows remote attackers to cause a denial of service =
(application crash)=E2=80=A6
etc.
Do you want to expose such lib to the potential attacker?
