vulnerability note CVE-2009-1355

AIX: buffer overflow of muxatmd

Synthesis of the vulnerability

A local attacker can use the /usr/sbin/muxatmd program in order to obtain the root privilege.
Impacted products: AIX.
Severity: 2/4.
Consequences: administrator access/rights.
Provenance: user shell.
Creation date: 16/04/2009.
Identifiers: BID-34543, CVE-2009-1355, VIGILANCE-VUL-8644.

Description of the vulnerability

The /usr/sbin/muxatmd daemon is part of the ATM subsystem (devices.common.IBM.atm.rte). This program is installed suid root.

The filename indicated as parameter of muxatmd is stored in a fixed size array. A long filename thus generates a buffer overflow.

A local attacker can therefore use the /usr/sbin/muxatmd program in order to obtain the root privilege.

vulnerability announce CVE-2009-1185 CVE-2009-1186

udev: privilege elevation

Synthesis of the vulnerability

A local attacker can use two udev vulnerabilities in order to execute code with kernel privileges.
Impacted products: Debian, Fedora, Linux, Mandriva Linux, openSUSE, RHEL, Slackware, SLES, ESX.
Severity: 2/4.
Consequences: administrator access/rights.
Provenance: user shell.
Number of vulnerabilities in this bulletin: 2.
Creation date: 16/04/2009.
Revision date: 20/04/2009.
Identifiers: 495051, 495052, BID-34536, BID-34539, CERTA-2009-AVI-155, CVE-2009-1185, CVE-2009-1186, DSA-1772-1, FEDORA-2009-3711, FEDORA-2009-3712, MDVSA-2009:103, MDVSA-2009:103-1, MDVSA-2009:104, RHSA-2009:0427-01, SSA:2009-111-01, SSA:2009-111-02, SUSE-SA:2009:020, SUSE-SA:2009:025, VIGILANCE-VUL-8642, VMSA-2009-0009.

Description of the vulnerability

The 2.6 kernel uses udev to manage /dev and hotplug devices. It is impacted by two vulnerabilities.

The NETLINK_KOBJECT_UEVENT message is sent on a PF_NETLINK socket by the kernel to an user space process. However, udev does not check if this message comes from the kernel space. It then accepts the associated action, such as creating a device. A local attacker can therefore obtain the root privilege. [severity:2/4; 495051, BID-34536, CERTA-2009-AVI-155, CVE-2009-1185]

The util_path_encode() function of the udev/lib/libudev-util.c file converts special characters to "\xXX" where XX is the hexadecimal code of the character. The final name is thus longer than the requested device name, but the function does not reserve sufficient space to store the new name. An attacker can therefore generate a buffer overflow. [severity:2/4; 495052, BID-34539, CVE-2009-1186]

A local attacker can therefore execute code with kernel privileges.

vulnerability alert CVE-2009-1285

phpMyAdmin: PHP code execution

Synthesis of the vulnerability

An attacker can inject PHP code in a phpMyAdmin configuration file, in order to execute it.
Impacted products: Fedora, phpMyAdmin.
Severity: 2/4.
Consequences: user access/rights.
Provenance: user account.
Creation date: 16/04/2009.
Identifiers: BID-34526, CERTA-2009-AVI-148, CVE-2009-1285, FEDORA-2009-3692, FEDORA-2009-3700, PMASA-2009-4, VIGILANCE-VUL-8641.

Description of the vulnerability

The phpMyAdmin server is used to administer a MySQL database via a web browser.

The setup/lib/ConfigFile.class.php file generates a configuration file for a database. This configuration file is written in PHP language and contains the server name inside a comment:
  /* Server: name */

However, if the name is "n*/code;/*", phpMyAdmin generates:
  /* Server: n*/code;/* */
Attacker's code then runs when PHP interprets the configuration file.

An authenticated attacker can thus inject PHP code in a phpMyAdmin configuration file, in order to execute it.

vulnerability CVE-2009-0792

Ghostscript: integer overflows via ICC

Synthesis of the vulnerability

An attacker can invite the victim to open a malicious PDF or PS file with Ghostscript in order to execute code with victim's privileges.
Impacted products: Debian, Fedora, Mandriva Linux, NLD, OES, OpenSolaris, openSUSE, Solaris, RHEL, Slackware, SLES, Unix (platform) ~ not comprehensive.
Severity: 2/4.
Consequences: user access/rights, client access/rights.
Provenance: document.
Creation date: 16/04/2009.
Identifiers: 262288, 491853, 6830965, 6837966, 6837974, 6841014, CERTA-2002-AVI-279, CVE-2009-0792, DSA-2080-1, FEDORA-2009-3430, FEDORA-2009-3435, FEDORA-2009-3709, FEDORA-2009-3710, FEDORA-2009-3720, FEDORA-2009-3740, MDVSA-2009:095, MDVSA-2009:096, MDVSA-2009:096-1, MDVSA-2009:311, RHSA-2009:0420-01, RHSA-2009:0421-01, SSA:2009-181-01, SUSE-SR:2009:009, SUSE-SR:2009:011, VIGILANCE-VUL-8640.

Description of the vulnerability

The ICC (International Color Consortium) profile defines color variations needed by each device in order to display identical colors. Some image types, such as JPEG or PNG, can contain ICC profiles and can be included in a PDF or PostScript document.

The icclib/icc.c file of Ghostscript implements ICC.

The VIGILANCE-VUL-8547 vulnerability describes several ICC integer overflows which lead to code execution. However, its patch was incomplete.

The icclib/icc.c file still contains several errors in the handling of integers coming from an ICC profile. These integer overflows can corrupt the memory.

An attacker can therefore invite the victim to open a malicious PDF or PS file with Ghostscript in order to execute code with victim's privileges.

vulnerability note CVE-2009-0077 CVE-2009-0237

ISA, Forefront: two vulnerabilities

Synthesis of the vulnerability

An attacker can generate a denial of service and a Cross Site Scripting in ISA Server and Forefront Threat Management Gateway.
Impacted products: ISA.
Severity: 3/4.
Consequences: client access/rights, denial of service on service.
Provenance: internet client.
Number of vulnerabilities in this bulletin: 2.
Creation date: 15/04/2009.
Identifiers: 961759, BID-34414, BID-34416, CERTA-2009-AVI-146, CVE-2009-0077, CVE-2009-0237, MS09-016, VIGILANCE-VUL-8634.

Description of the vulnerability

Two vulnerabilities impact ISA Server and Forefront Threat Management Gateway.

The Web proxy and Web listeners do not correctly manage the session closing. A TCP packet sequence thus generates a denial of service. [severity:3/4; BID-34414, CERTA-2009-AVI-146, CVE-2009-0077]

vulnerability bulletin CVE-2008-2540

Windows: code execution via SearchPath

Synthesis of the vulnerability

A library downloaded on the desktop can be loaded and leads to malicious code execution.
Impacted products: Windows 2000, Windows 2003, Windows 2008 R0, Windows Vista, Windows XP.
Severity: 2/4.
Consequences: user access/rights.
Provenance: document.
Creation date: 15/04/2009.
Identifiers: 959426, BID-29445, CVE-2008-2540, MS09-015, VIGILANCE-VUL-8633.

Description of the vulnerability

The SearchPath indicates the order of directories to search for libraries.

However, the SearchPath first contains the desktop before containing system directories. When a program calls an unloaded library, and if a file with the library name is located on the desktop, it is loaded.

This behaviour can therefore be used when the attacker:
 - can upload a file on the desktop with no warning (via Apple Safari for example)
 - can force a software to load a new library (via Internet Explorer opening a new format)

A library downloaded on the desktop can therefore be loaded and leads to malicious code execution.
