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
|
|
string.
|
|
</p>
|
|

|
|
<impact type="low">
|
|
<p>
|
|
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
|
|
libcurl.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All cURL users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.1"</code>
|
|
</resolution>
