<description>
|
|
<p>A bad sanitization of environment variables: CAML_CPLUGINS,
|
|
CAML_NATIVE_CPLUGINS and CAML_BYTE_CPLUGINS in the OCaml compiler allows
|
|
the execution of raised privileges via external code.
|
|
</p>

|
|
<impact type="high">
|
|
<p>A local attacker, by using specially crafted environment variables,
|
|
could possibly escalate privileges to the root group.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All OCaml users should upgrade to the latest version:</p>
|

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-lang/ocaml-4.04.2"
