ISS X-Force Database: linux-kernel-ptraceattach-dos(43567): Linux kernel PTRACE

Linux kernel PTRACE_ATTACH denial of service

linux-kernel-ptraceattach-dos (43567)

Medium Risk

Description:

The Linux kernel, when running on certain versions of Red Hat Enterprise Linux and possibly other Linux distributions, is vulnerable to a denial of service, caused by a race condition in the ptrace and utrace support. A local attacker could exploit this vulnerability by sending a long series of PTRACE_ATTACH ptrace calls to another user's process to cause the kernel to crash.

*CVSS:

Base Score:	2.1
Access Vector:	Local
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Partial

Temporal Score:	1.6
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of the Linux kernel (2.6.25.10 or later), available from The Linux Kernel Archives Web site. See References.

For other distributions:
Apply the appropriate update for your system. See References.
