ISS X-Force Database: linux-kernel-tmpfs-dos(44489): Linux kernel tmpfs denial of service

Linux kernel tmpfs denial of service

linux-kernel-tmpfs-dos (44489)

Medium Risk

Description:

The Linux kernel is vulnerable to a denial of service, caused by an error in the tmpfs shmem_delete_inode() function. A local attacker could exploit this vulnerability via the insserv program using certain file operations to cause the system to crash.

*CVSS:

Base Score:	4.9
Access Vector:	Local
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Complete

Temporal Score:	4.3
Exploitability:	High
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of the Linux kernel (2.6.26.1 or later), available from the Linux Kernel GIT Repository. See References.

BID-31134: Linux Kernel 'shmem_delete_inode()' Local Denial of Service Vulnerability
CVE-2008-3534: The shmem_delete_inode function in mm/shmem.c in the tmpfs implementation in the Linux kernel before 2.6.26.1 allows local users to cause a denial of service (system crash) via a certain sequence of file create, remove, and overwrite operations, as demonstrated by the insserv program, related to allocation of useless pages and improper maintenance of the i_blocks count.
