ISS X-Force Database: linux-kernel-pppol2tprecvmsg-dos(43111): Linux Kernel pppol2tp

Linux Kernel pppol2tp_recvmsg() denial of service

linux-kernel-pppol2tprecvmsg-dos (43111)

Medium Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by improper bounds checking by the pppol2tp_recvmsg() function. By sending a specially crafted PPP over L2TP packet, a remote attacker from within the local network could exploit this vulnerability to corrupt kernel memory and cause a denial of service.

*CVSS:

Base Score:	3.3
Access Vector:	Adjacent Network
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Partial

Temporal Score:	2.4
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of Linux Kernel (2.6.26-rc6 or later), available from The Linux Kernel Archives Web site. See References.

BID-29747: Linux Kernel 'pppol2tp_recvmsg()' Remote Denial of Service Vulnerability
CVE-2008-2750: The pppol2tp_recvmsg function in drivers/net/pppol2tp.c in the Linux kernel 2.6 before 2.6.26-rc6 allows remote attackers to cause a denial of service (kernel heap memory corruption and system crash) and possibly have unspecified other impact via a crafted PPPOL2TP packet that results in a large value for a certain length variable.
