ISS X-Force Database: linux-kernel-dochangetype-priv-escalation(43696): Linux kernel do_change

Linux kernel do_change_type function privilege escalation

linux-kernel-dochangetype-priv-escalation (43696)

High Risk

Description:

The Linux kernel could allow a local attacker to gain elevated privileges, caused by improper verification of caller CAP_SYS_ADMIN capability in the do_change_type function. By modifying the properties of a mountpoint, an attacker could gain elevated privileges or cause a denial of service.

*CVSS:

Base Score:	4.6
Access Vector:	Local
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	Partial
Integrity Impact:	Partial
Availability Impact:	Partial

Temporal Score:	3.4
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Gain Privileges

Remedy:

Refer to Red Hat Bugzilla Bug 454388 for patch, upgrade or suggested workaround information. See References.

CVE-2008-2931: The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.
