Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
An error in acpid might allow remote attackers to cause a Denial of
Service.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
acpid is a daemon for the Advanced Configuration and Power Interface
(ACPI).
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-power/acpid < 1.0.10 >=3D 1.0.10
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The acpid daemon allows opening a large number of UNIX sockets without
closing them, triggering an infinite loop.
Impact
=3D=3D=3D=3D=3D=3D
Remote attackers can cause a Denial of Service (CPU consumption and
connectivity loss).
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All acpid users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dsys-power/acpid-1.0.10"
