computer vulnerability note 19249

Node.js restafary: directory traversal

Synthesis of the vulnerability

An attacker can traverse directories of Node.js restafary, in order to read a file outside the service root path.
Impacted products: Nodejs Modules ~ not comprehensive.
Severity: 2/4.
Consequences: data reading.
Provenance: internet client.
Creation date: 29/03/2016.
Identifiers: VIGILANCE-VUL-19249.

Description of the vulnerability

The restafary module can be installed on Node.js.

However, user's data are directly inserted in an access path. Sequences such as "/.." can thus be used to go in the upper directory.

An attacker can therefore traverse directories of Node.js restafary, in order to read a file outside the service root path.

computer vulnerability bulletin CVE-2016-3158 CVE-2016-3159

Xen: information disclosure during arithmetic operations

Synthesis of the vulnerability

When Xen is installed on AMD processors Family 15 (or greater), an attacker located in a guest system can obtain information during arithmetic operations.
Impacted products: XenServer, Debian, Fedora, openSUSE, openSUSE Leap, SUSE Linux Enterprise Desktop, SLES, Xen.
Severity: 1/4.
Consequences: data reading.
Provenance: user shell.
Number of vulnerabilities in this bulletin: 2.
Creation date: 29/03/2016.
Identifiers: CERTFR-2016-AVI-133, CTX209443, CVE-2016-3158, CVE-2016-3159, DLA-571-1, DSA-3554-1, FEDORA-2016-5f196e4e4a, FEDORA-2016-e5432ca977, openSUSE-SU-2016:2494-1, openSUSE-SU-2016:2497-1, SUSE-SU-2016:2093-1, SUSE-SU-2016:2100-1, SUSE-SU-2016:2528-1, SUSE-SU-2016:2533-1, SUSE-SU-2016:2725-1, VIGILANCE-VUL-19248, XSA-172.

Description of the vulnerability

The Floating Point Unit (FPU, x87) is used during floating point arithmetic operations. The FPU contains 3 debug registers: FOP, FIP and FDP. The FSAVE/FSTOR or FXSAVE/FXSTOR instructions save and restore these registers. The support is enabled via the "xsave" option.

The xrstor() function of the xen/arch/x86/i387.c file does not manage the case of AMD processor, which require these registers to be erased, even if FSW.ESis used (to fix VIGILANCE-VUL-12901). So, a guest system can access to the content of the FOP, FIP and FDP registers of another domain.

When Xen is installed on AMD processors Family 15 (or greater), an attacker located in a guest system can therefore obtain information during arithmetic operations.

computer vulnerability announce CVE-2015-7552

GDK-PixBuf: buffer overflow

Synthesis of the vulnerability

An attacker can generate a buffer overflow of GDK-PixBuf, in order to trigger a denial of service, and possibly to run code.
Impacted products: Debian, openSUSE, openSUSE Leap, Slackware, Ubuntu.
Severity: 2/4.
Consequences: user access/rights, denial of service on service, denial of service on client.
Provenance: document.
Creation date: 29/03/2016.

computer vulnerability alert 19246

Node.js: code execution via npm

Synthesis of the vulnerability

An attacker can invite the victim to install a malicious package with npm of Node.js, in order to run code.
Impacted products: Nodejs Modules ~ not comprehensive.
Severity: 2/4.
Consequences: user access/rights.
Provenance: document.
Creation date: 29/03/2016.
Identifiers: VIGILANCE-VUL-19246, VU#319816.

Description of the vulnerability

The Node.js product uses npm to manage packages.

However, a malicious package can contain scripts, which are run during the installation, or during its usage.

If the victim has publication privileges, a worm can use these scripts to inject itself in new packages published on the internet.

An attacker can therefore invite the victim to install a malicious package with npm of Node.js, in order to run code.
