Insight
Insight
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.
