Will Drewry (Google Security) reported a vulnerability in the regular
|
|
expression engine when using back references to capture \0 characters
|
|
(CVE-2007-4770). He also found that the backtracking stack size is not
|
|
limited, possibly allowing for a heap-based buffer overflow
|
|
(CVE-2007-4771).

<impact type="high">
|
|
<p>
|
|
A remote attacker could submit specially crafted regular expressions to
|
|
an application using the library, possibly resulting in the remote
|
|
execution of arbitrary code with the privileges of the user running the
|
|
application or a Denial of Service.
|

|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>
|

<resolution>
|
|
<p>
|
|
All International Components for Unicode users should upgrade to the
|
|
latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/icu-3.8.1-r1"</code>
