(cURL: Off-by-one errors in URL handling)
Stefan Esser from the Hardened-PHP Project has reported a
vulnerability in cURL that allows for a local buffer overflow when cURL
attempts to parse specially crafted URLs. The URL can be specially

hostname portion, which causes a '/' to be prepended to the resulting
An attacker capable of getting cURL to parse a maliciously crafted
URL could cause a denial of service or execute arbitrary code with the

escape open_basedir or safe_mode pseudo-restrictions when exploiting
this problem from within a PHP program when PHP is compiled with
