ISS X-Force Database: kernel-htx-signal-dos(35383): Linux kernel on PowerPC using HTX signal handling denial of service

Linux kernel on PowerPC using HTX signal handling denial of service

kernel-htx-signal-dos (35383)

Low Risk

Description:

The Linux kernel on PowerPC using HTX is vulnerable to a denial of service, caused by a vulnerability in the signal handling service. A local attacker could exploit this vulnerability to cause a denial of service.

*CVSS:

Base Score:	2.5
Access Vector:	Local
Access Complexity:	Low
Authentication:	Not Required
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Partial

Temporal Score:	1.8
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

For Red Hat Linux:
Refer to RHSA-2007:0595 for patch, upgrade, or suggested workaround information. See References.

For SUSE Linux (kernel):
