Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Reachable assertion (CVE-ID: CVE-2019-15604)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of X509 certificates in X509V3_EXT_print(). A remote attacker can supply a specially crafted client certificate to the application and perform a denial of service attack.


2) HTTP request smuggling (CVE-ID: CVE-2019-15605)

The vulnerability allows a remote attacker to perform HTTP request smuggling attack.

The vulnerability exists due to insufficient validation of Transfer-Encoding header. A remote attacker can send a specially crafted HTTP request to the application and perform a request smuggling attack.


3) Input validation error (CVE-ID: CVE-2019-15606)

The vulnerability allows a remote attacker to manipulate HTTP headers.

The vulnerability exists due to insufficient validation of a trailing white-space character in the request headers. A remote attacker can send a specially crafted HTTP request to the application and bypass certain security restrictions.


4) Symlink following (CVE-ID: CVE-2019-16775)

The vulnerability allows a remote attacker to perform directory traversal attacks.

Versions of the npm CLI prior to 6.13.3 are vulnerable to a symlink reference outside of node_modules. It is possible for packages to create symlinks to files outside of the node_modules folder through the bin field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user’s system when the package is installed. Only files accessible by the user running the npm install are affected.


5) Improper input validation (CVE-ID: CVE-2019-16776)

The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the JavaScript (Node.js) component in Oracle GraalVM Enterprise Edition. A remote authenticated user can exploit this vulnerability to read and manipulate data.


6) Path traversal (CVE-ID: CVE-2019-16777)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. The software fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the first binary. This only affects files in /usr/local/bin

A remote attacker can overwrite arbitrary files on the system.
