Description

This security bulletin contains information about 4 vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2014-0075)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to integer overflow in the parseChunkHeader function in java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat. A remote attacker can cause a denial of service (resource consumption) via a malformed chunk size in chunked transfer coding of a request during the streaming of data.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2014-0096)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat does not properly restrict XSLT stylesheets. A remote attacker can bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.


3) Integer overflow (CVE-ID: CVE-2014-0099)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat when operated behind a reverse proxy. A remote attacker can conduct HTTP request smuggling attack via a crafted Content-Length HTTP header.


4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2014-0227)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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

The vulnerability exists due to java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat does not properly handle attempts to continue reading data after an error has occurred. A remote attacker can conduct HTTP request smuggling attacks or cause a denial of service (resource consumption) by streaming data with malformed chunked transfer coding.
