| Detailed Description |
According to its self-reported version number, the instance of Apache Tomcat 6.0 listening on the remote host is earlier than Tomcat 6.0.44 and, therefore, may be affected by the following vulnerabilities :
- An error exists due to a failure to limit the size of discarded requests. A remote attacker can exploit this to exhaust available memory resources, resulting in a denial of service condition.
- A NULL pointer dereference flaw exists when the SSLv3 option isn't enabled and an SSLv3 ClientHello is received. This allows a remote attacker, using an unexpected handshake, to crash the daemon.
- The BIGNUM squaring (BN_sqr) implementation does not properly calculate the square of a BIGNUM value. This allows remote attackers to defeat cryptographic protection mechanisms.
- A NULL pointer dereference flaw exists with dtls1_get_record when handling DTLS messages. A remote attacker, using a specially crafted DTLS message, can cause a denial of service.
- A flaw exists with ECDH handshakes when using an ECDSA certificate without a ServerKeyExchange message. This allows a remote attacker to trigger a loss of forward secrecy from the ciphersuite.
- A malicious application can use expression language to bypass the internal Security Manager and execute code with elevated privileges.
- A flaw exists when accepting non-DER variations of certificate signature algorithms and signature encodings due to a lack of enforcement of matches between signed and unsigned portions. A remote attacker, by including crafted data within a certificate's unsigned portion, can bypass fingerprint-based certificate-blacklist protection mechanisms.
- A flaw exists when handling an RSA temporary key in a non-export RSA key exchange ciphersuite. This allows a remote attacker to downgrade the security of the session.
- A flaw exists when accepting DH certificates for client authentication without the CertificateVerify message. This allows a remote attacker to authenticate to the service without a private key.
- A memory leak occurs in dtls1_buffer_record when handling a saturation of DTLS records containing the same number sequence but for the next epoch. This allows a remote attacker to cause a denial of service.
- A use-after-free condition exists in the d2i_ECPrivateKey() function due to improper processing of malformed EC private key files during import. A remote attacker can exploit this to dereference or free already freed memory, resulting in a denial of service or other unspecified impact.
- An invalid read flaw exists in the ASN1_TYPE_cmp() function due to improperly performed boolean-type comparisons. A remote attacker can exploit this, via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature, to cause an invalid read operation, resulting in a denial of service.
- A flaw exists in the ASN1_item_ex_d2i() function due to a failure to reinitialize 'CHOICE' and 'ADB' data structures when reusing a structure in ASN.1 parsing. This allows a remote attacker to cause an invalid write operation and memory corruption, resulting in a denial of service.
- A NULL pointer dereference flaw exists in the X509_to_X509_REQ() function due to improper processing of certificate keys. This allows a remote attacker, via a crafted X.509 certificate, to cause a denial of service.
- A NULL pointer dereference flaw exists in the PKCS#7 parsing code due to incorrect handling of missing outer ContentInfo. This allows a remote attacker, using an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, to cause a denial of service.
- A flaw exists in servers that both support SSLv2 and enable export cipher suites due to improper implementation of SSLv2. A remote attacker can exploit this, via a crafted CLIENT-MASTER-KEY message, to cause a denial of service.
