Tavis Ormandy reported that Valgrind loads a .valgrindrc file in the
|
||
|
|
current working directory, executing commands specified there.

<impact type="high">
|
||
|
|
<p>
|
||
|
|
A local attacker could prepare a specially crafted .valgrindrc file and
|
||
|
|
entice a user to run Valgrind from the directory containing that file,
|
||
|
|
resulting in the execution of arbitrary code with the privileges of the
|
||
|
|
user running Valgrind.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
Do not run "valgrind" from untrusted working directories.
|
||
|
|
</p>
|
||
|
|
</workaround>
|
||
|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All Valgrind users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=dev-util/valgrind-3.4.0"</code>
