CVE-2011-3153 [LOW] Light Display Manager vulnerabilities
Title: Light Display Manager vulnerabilities
Summary: Several security issues were fixed in Light Display Manager.
It was discovered that Light Display Manager incorrectly handled privileges
when reading .dmrc files. A local attacker could exploit this issue to read
arbitrary configuration files, bypassing intended permissions.
(CVE-2011-3153)
It was discovered that Light Display Manager incorrectly handled links when
adjusting permissions on .Xauthority files. A local attacker could exploit
this issue to access arbitrary files, and possibly obtain increased
privileges. In the default Ubuntu installation, this would be prevented
by the Yama link restrictions. (CVE-2011-4105)
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.
