with escalated privileges.

Pulseaudio is a networked sound server with an advanced plugin system.
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">
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.
There is no known workaround at this time.
All Pulseaudio users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-sound/pulseaudio-0.9.9&quot;</code>
