Computer vulnerabilities of RedHat JBoss EAP

vulnerability CVE-2014-0230

Apache Tomcat: denial of service via SwallowSize

Synthesis of the vulnerability

An attacker can upload an invalid file on Apache Tomcat, to consume a large amount of memory, in order to trigger a denial of service.
Impacted products: Tomcat, Debian, BIG-IP Hardware, TMOS, HP-UX, Oracle Communications, Solaris, RealPresence Collaboration Server, RealPresence Resource Manager, JBoss EAP by Red Hat, Ubuntu.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service, denial of service on client.
Provenance: internet client.
Creation date: 10/04/2015.
Identifiers: bulletinoct2015, c05054964, CERTFR-2015-AVI-204, cpujul2018, CVE-2014-0230, DSA-3530-1, HPSBUX03561, RHSA-2015:1621-01, RHSA-2015:1622-01, RHSA-2015:2659-01, RHSA-2015:2660-01, RHSA-2015:2661-01, RHSA-2016:0595-01, RHSA-2016:0596-01, RHSA-2016:0597-01, RHSA-2016:0599-01, SOL17123, USN-2654-1, USN-2655-1, VIGILANCE-VUL-16570.

Description of the vulnerability

The Apache Tomcat product offers a web service, which can accept the file upload feature.

However, when the tomcat server expects to refuse an upload, it still accepts to read the received file without a memory limit.

An attacker can therefore upload an invalid file on Apache Tomcat, to consume a large amount of memory, in order to trigger a denial of service.

Description of the vulnerability

An SSL/TLS session can be established using several protocols:
 - SSL 2.0 (obsolete)
 - SSL 3.0
 - TLS 1.0
 - TLS 1.1
 - TLS 1.2

An attacker can downgrade the version to SSLv3. However, with SSL 3.0, an attacker can change the padding position with a CBC encryption, in order to progressively guess clear text fragments.

This vulnerability is named POODLE (Padding Oracle On Downgraded Legacy Encryption).

An attacker, located as a Man-in-the-Middle, can therefore decrypt a SSL 3.0 session, in order to obtain sensitive information.

Description of the vulnerability

The HttpClient library can manage HTTP connections over SSL.

In order to authenticate a server, the client must check the certificate (cryptographic signatures, validity date range, etc.) and also that the received certificate matches the visited server. This check is usually done on DNS names, or sometimes on IP addresses. However, instead of looking the exact field subjectAltName or, for compatibility, the commonName field, the library looks fro a substring that matches the targeted server name.

This vulnerability is a variant of VIGILANCE-VUL-12182.

An attacker can therefore create an SSL certificate which will be wrongly validated by Apache HttpComponents HttpClient, in order to capture traffic and bypass encryption.

Description of the vulnerability

Several vulnerabilities were announced in OpenSSL.

An attacker can send DTLS packets that will lead to double free of memory and then a crash, in order to trigger a denial of service. [severity:3/4; CVE-2014-3505]

An attacker can make an application consumes a large amount of memory in the processing of DTLS handshake packets, in order to trigger a denial of service. [severity:3/4; CVE-2014-3506]

An attacker can create a memory leak in the DTLS packet processing, in order to trigger a denial of service. [severity:3/4; CVE-2014-3507]

A server attacker can force a NULL pointer to be dereferenced in the handshake processing if the client supports key exchange with anonymous Diffie-Hellman, in order to trigger a denial of service. [severity:2/4; CVE-2014-3510]

A client attacker can force use of TLS 1.0 by special fragmentation of the Client Hello message, in order to reduce the strength of negotiated algorithms. [severity:1/4; CVE-2014-3511]

An attacker can generate a buffer overflow in the processing of SRP parameters, in order to trigger a denial of service, and possibly to execute code. [severity:3/4; CVE-2014-3512]

An attacker can force a NULL pointer to be dereferenced in the TLS client by asserting support for SRP, in order to trigger a denial of service. [severity:2/4; CVE-2014-5139]

Description of the vulnerability

The mod_cgid module of Apache httpd manages CGI scripts.

However, if a CGI script does not consume its standard input, the child process hangs indefinitely.

An attacker, who is allowed to upload a malicious CGI script on the server, can therefore block mod_cgid of Apache httpd, in order to trigger a denial of service.

Apache httpd: denial of service via mod_deflate

Synthesis of the vulnerability

An attacker can send special data to Apache httpd with mod_deflate as an Input Filter, in order to trigger a denial of service.
Impacted products: Apache httpd, Apache httpd Modules ~ not comprehensive, Debian, Fedora, HP-UX, WebSphere AS Traditional, NSMXpress, Solaris, Puppet, RHEL, JBoss EAP by Red Hat, SAS Add-in for Microsoft Office, SAS Analytics Pro, Base SAS Software, SAS Enterprise BI Server, SAS Enterprise Guide, SAS Management Console, SAS OLAP Server, SAS SAS/ACCESS, SAS SAS/AF, SAS SAS/CONNECT, SAS SAS/EIS, SAS SAS/ETS, SAS SAS/FSP, SAS SAS/GRAPH, SAS SAS/IML, SAS SAS/OR, SAS SAS/STAT, SAS SAS/Web Report Studio, Slackware, Ubuntu.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service.
Provenance: internet client.
Creation date: 17/07/2014.
Identifiers: 1690185, 1695392, 7036319, c04686230, c04832246, CERTFR-2015-AVI-286, CVE-2014-0118, DSA-2989-1, FEDORA-2014-8742, FEDORA-2014-9057, HPSBUX03337, HPSBUX03512, JSA10685, MDVSA-2014:142, MDVSA-2015:093, RHSA-2014:0920-01, RHSA-2014:0921-01, RHSA-2014:0922-01, RHSA-2014:1019-01, RHSA-2014:1020-01, RHSA-2014:1021-01, RHSA-2014:1086-01, RHSA-2014:1087-01, RHSA-2014:1088-01, SSA:2014-204-01, SSRT102066, SSRT102254, USN-2299-1, VIGILANCE-VUL-15067.

Description of the vulnerability

The mod_deflate module of Apache httpd compresses/uncompresses data.

The decompression of the HTTP body is for example enabled with:
  <Location /dav-area>
    SetInputFilter DEFLATE
  </Location>

However, in this case, special data lead to the consumption of several resources.

An attacker can therefore send special data to Apache httpd with mod_deflate as an Input Filter, in order to trigger a denial of service.
