Package : acpid
Vulnerability : several
Problem type : remote
Debian-specific: partly
CVE ID : CVE-2011-1159 CVE-2011-2777 CVE-2011-4578
Multiple vulnerabilities were found in the acpid, the Advanced
Configuration and Power Interface event daemon:
CVE-2011-1159
Vasiliy Kulikov of OpenWall discovered that the socket handling
is vulnerable to denial of service.
CVE-2011-2777
Oliver-Tobias Ripka discovered that incorrect process handling in
the Debian-specific powerbtn.sh script could lead to local
privilege escalation. This issue doesn't affect oldstable. The
script is only shipped as an example in /usr/share/doc/acpid/examples.
See /usr/share/doc/acpid/README.Debian for details.
CVE-2011-4578
Helmut Grohne and Michael Biebl discovered that acpid sets a umask
of 0 when executing scripts, which could result in local privilege
escalation.
For the oldstable distribution (lenny), this problem has been fixed in
version 1.0.8-1lenny4.
For the stable distribution (squeeze), this problem has been fixed in
version 1:2.0.7-1squeeze3.
For the unstable distribution (sid), this problem will be fixed soon.
We recommend that you upgrade your acpid packages.
