Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2011-1006)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the parse_cgroup_spec function in tools/tools-common.c in the Control Group Configuration Library (aka libcgroup or libcg) before 0.37.1. A remote attacker can use a crafted controller list on the command line of an application. NOTE to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2011-1022)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The cgre_receive_netlink_msg function in daemon/cgrulesengd.c in cgrulesengd in the Control Group Configuration Library (aka libcgroup or libcg) before 0.37.1 does not verify that netlink messages originated in the kernel, which allows local users to bypass intended resource restrictions via a crafted message.
