Description :

The remote host is affected by the vulnerability described in GLSA-200512-09
(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
crafted in one of two ways: the URL could be malformed in a way that
prevents a terminating null byte from being added to either a hostname
or path buffer; or the URL could contain a '?' separator in the
hostname portion, which causes a '/' to be prepended to the resulting

Impact :

An attacker capable of getting cURL to parse a maliciously crafted
URL could cause a denial of service or execute arbitrary code with the
privileges of the user making the call to cURL. An attacker could also
escape open_basedir or safe_mode pseudo-restrictions when exploiting
this problem from within a PHP program when PHP is compiled with

Workaround :

There is no known workaround at this time.
