vulnerability CVE-2012-4842 CVE-2012-4844

IBM Lotus Domino: Cross Site Scripting via Login

Synthesis of the vulnerability

An attacker, who is authenticated in IBM Lotus Domino, can invite other users to display a malicious HTML page, in order to trigger a Cross Site Scripting, to execute JavaScript code in the context of their browsers.
Impacted products: Domino, Notes.
Severity: 1/4.
Consequences: client access/rights.
Provenance: document.
Number of vulnerabilities in this bulletin: 2.
Creation date: 18/02/2013.
Identifiers: BID-58152, CVE-2012-4842, CVE-2012-4844, SPR KLYH8WBPRN, swg21614077, VIGILANCE-VUL-12430.

Description of the vulnerability

The "/names.nsf?Login" page is used during the authentication.

The RedirectTo parameter of the authentication form redirects users, once they are authenticated. However, the content of this parameter is directly injected in the generated HTML page.

An attacker, who is authenticated in IBM Lotus Domino, can therefore invite other users to display a malicious HTML page, in order to trigger a Cross Site Scripting, to execute JavaScript code in the context of their browsers.

computer vulnerability bulletin 12428

Windows 7: denial of service via ZwSetInformationProcess

Synthesis of the vulnerability

An attacker can use the ZwSetInformationProcess() function, in order to change the priority of the current process, so it is not killable, or to stop the system.
Impacted products: Windows 7.
Severity: 1/4.
Consequences: denial of service on server.
Provenance: user shell.
Number of vulnerabilities in this bulletin: 2.
Creation date: 15/02/2013.
Identifiers: BID-57961, VIGILANCE-VUL-12428.

Description of the vulnerability

The undocumented ZwSetInformationProcess() function from NTDLL, is used to modify the state of a process.

The ProcessIoPriority (0x21) parameter changes its priority. An attacker is not allowed to change the priority of his process. However, using a negative priority, the check is bypassed, and this leads to two vulnerabilities.

An attacker can set the ProcessSelfDelete flag, in order to create a process which cannot be killed. [severity:1/4]

An attacker can set the SetTimerResolutionLink flag, in order to dereference a NULL pointer, which stops the system. [severity:1/4]

An attacker can therefore use the ZwSetInformationProcess() function, in order to change the priority of the current process, so it is not killable, or to stop the system.

computer vulnerability announce CVE-2013-0290

Linux kernel: denial of service via __skb_recv_datagram

Synthesis of the vulnerability

A local attacker can send an empty message to a SOCK_DGRAM socket, in order to create an infinite loop in the kernel.
Impacted products: Fedora, Linux, openSUSE, RHEL.
Severity: 1/4.
Consequences: denial of service on server.
Provenance: user shell.
Creation date: 15/02/2013.
Identifiers: BID-57964, CERTA-2013-AVI-375, CVE-2013-0290, FEDORA-2013-2597, FEDORA-2013-2635, MDVSA-2013:176, openSUSE-SU-2013:0951-1, openSUSE-SU-2013:1042-1, RHSA-2013:0622-01, VIGILANCE-VUL-12427.

Description of the vulnerability

The sendmsg() and recvmsg() functions are used to send and receive messages on a socket. The option MSG_PEEK of recvmsg() is used to check the availability of a message.

The __skb_recv_datagram() function of the net/core/datagram.c file implements recvmsg() on SOCK_DGRAM sockets. However, if the message has a size of zero, the __skb_recv_datagram() function continues to loop, searching for a message.

A local attacker can therefore send an empty message to a SOCK_DGRAM socket, in order to create an infinite loop in the kernel.

computer vulnerability CVE-2013-0281

Pacemaker: denial of service via socket

Synthesis of the vulnerability

An attacker can connect to the Pacemaker socket, in order to block it.
Impacted products: Pacemaker, RHEL.
Severity: 2/4.
Consequences: denial of service on service.
Provenance: intranet client.
Creation date: 14/02/2013.
Identifiers: BID-57965, CVE-2013-0281, RHSA-2013:1635-02, VIGILANCE-VUL-12425.

Description of the vulnerability

The Pacemaker service uses a network socket to communicate. The access to this socket requires an authentication.

However this socket is blocking (no inactivity timeout). An attacker can thus connect, without authenticating, in order to block the application.

An attacker can therefore connect to the Pacemaker socket, in order to block it.

vulnerability bulletin CVE-2013-0228

Xen: denial of service via 32 bit PVOPS and DS

Synthesis of the vulnerability

On a Linux 32 bit PVOPS system, a local attacker can change the DS register, in order to stop the system.
Impacted products: Fedora, Linux, RHEL, Unix (platform) ~ not comprehensive.
Severity: 1/4.
Consequences: denial of service on server.
Provenance: user shell.
Creation date: 14/02/2013.
Identifiers: BID-57940, CERTA-2013-AVI-132, CERTA-2013-AVI-375, CVE-2013-0228, FEDORA-2013-2597, MDVSA-2013:176, RHSA-2013:0630-01, VIGILANCE-VUL-12423, XSA-42.

Description of the vulnerability

The PVOPS (ParaVirtualized OPerationS) architecture is used to start a kernel on a real (or HVM) computer, or in a paravirtualized environment.

The %DS register is used to select a memory segment.

When Xen returns from an interruption, the xen_iret() function of the arch/x86/xen/xen-asm_32.S file uses %DS, without checking if it is still valid. However, an attacker can set %DS to zero, in order to trigger a fatal error.

On a Linux 32 bit PVOPS system, a local attacker can therefore change the DS register, in order to stop the system.
