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

…allows remote attackers to cause a denial of service (application crash)…
etc.

Do you want to expose such lib to the potential attacker?
