Gentoo: GLSA-201204-06: PolicyKit: Multiple vulnerabilities
Summary
Multiple vulnerabilities have been found in PolicyKit:
* Error messages in the pkexec utility disclose the existence of local
files (CVE-2010-0750).
* The pkexec utility initially checks the effective user ID of its
parent process for authorization, instead of checking the real user
ID (CVE-2011-1485).
* Members of the "wheel" group are able to execute commands as an
administrator without a password (CVE-2011-4945).
Resolution
All PolicyKit users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-auth/polkit-0.104-r1"
