Synopsis ========
A vulnerability in pulseaudio may allow a local user to execute actions with escalated privileges.
Background ==========
Pulseaudio is a networked sound server with an advanced plugin system.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-sound/pulseaudio < 0.9.9 >= 0.9.9
Description ===========
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 ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Pulseaudio users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-sound/pulseaudio-0.9.9"
References ==========
