Apache Tomcat 6.0.x < 6.0.43 Multiple Vulnerabilities (POODLE)

high Nessus Plugin ID 81649
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Apache Tomcat service listening on the remote host is 6.0.x prior to 6.0.43. It is, therefore, affected by the following vulnerabilities :

- An error exists in the function 'ssl3_read_bytes' that can allow data to be injected into other sessions or allow denial of service attacks. Note that this issue is exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2010-5298)

- A buffer overflow error exists related to invalid DTLS fragment handling that can lead to the execution of arbitrary code. Note that this issue only affects OpenSSL when used as a DTLS client or server.
(CVE-2014-0195)

- An error exists in the function 'do_ssl3_write' that can allow a NULL pointer to be dereferenced leading to denial of service attacks. Note that this issue is exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2014-0198)

- An error exists related to DTLS handshake handling that can lead to denial of service attacks. Note that this issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An unspecified error exists in how ChangeCipherSpec messages are processed that can allow an attacker to cause usage of weak keying material, leading to simplified man-in-the-middle attacks. (CVE-2014-0224)

- An unspecified error exists related to anonymous ECDH cipher suites that can allow denial of service attacks.
Note that this issue only affects OpenSSL TLS clients.
(CVE-2014-3470)

- A memory double-free error exists in 'd1_both.c' related to handling DTLS packets that allows denial of service attacks. (CVE-2014-3505)

- An unspecified error exists in 'd1_both.c' related to handling DTLS handshake messages that allows denial of service attacks due to large amounts of memory being consumed. (CVE-2014-3506)

- A memory leak error exists in 'd1_both.c' related to handling specially crafted DTLS packets that allows denial of service attacks. (CVE-2014-3507)

- An error exists in the 'OBJ_obj2txt' function when various 'X509_name_*' pretty printing functions are used, which leak process stack data, resulting in an information disclosure. (CVE-2014-3508)

- An error exists related to 'ec point format extension' handling and multithreaded clients that allows freed memory to be overwritten during a resumed session.
(CVE-2014-3509)

- A NULL pointer dereference error exists related to handling anonymous ECDH cipher suites and crafted handshake messages that allows denial of service attacks against clients. (CVE-2014-3510)

- An error exists related to handling fragmented 'ClientHello' messages that allows a man-in-the-middle attacker to force usage of TLS 1.0 regardless of higher protocol levels being supported by both the server and the client. (CVE-2014-3511)

- Buffer overflow errors exist in 'srp_lib.c' related to handling Secure Remote Password protocol (SRP) parameters, which can allow a denial of service or have other unspecified impact. (CVE-2014-3512)

- A memory leak issue exists in 'd1_srtp.c' related to the DTLS SRTP extension handling and specially crafted handshake messages that can allow denial of service attacks. (CVE-2014-3513)

- An error exists related to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode.
Man-in-the-middle attackers can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. This is also known as the 'POODLE' issue. (CVE-2014-3566)

- A memory leak issue exists in 't1_lib.c' related to session ticket handling that can allow denial of service attacks. (CVE-2014-3567)

- An error exists related to the build configuration process and the 'no-ssl3' build option that allows servers and clients to process insecure SSL 3.0 handshake messages. (CVE-2014-3568)

- A NULL pointer dereference error exists in 't1_lib.c', related to handling Secure Remote Password protocol (SRP) ServerHello messages, which allows a malicious server to crash a client, resulting in a denial of service. (CVE-2014-5139)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Update to Apache Tomcat version 6.0.43 or later.
