Multiple vulnerabilities in libcgroup

1) Heap-based buffer overflow

EUVDB-ID: #VU45179

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2011-1006

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

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.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU45180

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2011-1022

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
