Marcus Meissner from SUSE reported that the pa_drop_root() function
|
||
|
|
does not properly check the return value of the system calls setuid(),
|
||
|
|
seteuid(), setresuid() and setreuid() when dropping its privileges.

<impact type="high">
|
||
|
|
<p>
|
||
|
|
A local attacker could cause a resource exhaustion to make the system
|
||
|
|
calls fail, which would cause Pulseaudio to run as root. The attacker
|
||
|
|
could then perform actions with root privileges.
|
||
|
|

|
||
|

</impact>
|

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

<resolution>

|
<p>
|
||
|
|
All Pulseaudio users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=media-sound/pulseaudio-0.9.9"</code>
