Synopsis :

The remote web server is affected by multiple vulnerabilities.

Description :

According to the web server's banner, the version of HP System
Management Homepage (SMH) hosted on the remote web server is prior to
7.5.0. It is, therefore, affected by multiple vulnerabilities :

- An flaw exists within the 'mod_deflate' module when
handling highly compressed bodies. A remote attacker can
exploit this, via a specially crafted request, to
exhaust memory and CPU resources, resulting in a denial
of service condition. (CVE-2014-0118)

- The 'mod_status' module contains a race condition that
can be triggered when handling the scoreboard. A remote
attacker can exploit this to cause a denial of service,
execute arbitrary code, or obtain sensitive credential
information. (CVE-2014-0226)

- The 'mod_cgid' module lacks a time out mechanism. A
remote attacker can exploit this, via a specially
crafted request, to cause child processes to linger
indefinitely, filling up the scoreboard and resulting in
a denial of service vulnerability. (CVE-2014-0231)

- A flaw exists in WinNT MPM versions 2.4.1 to 2.4.9 when
using the default AcceptFilter. An attacker can exploit
this, via specially crafted requests. to create a memory
leak, resulting in a denial of service condition.
(CVE-2014-3523)

- 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, resulting in
a denial of service. (CVE-2014-3569)

- 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. (CVE-2014-3570)

- A NULL pointer dereference flaw exists in the
dtls1_get_record() function when handling DTLS messages.
A remote attacker, using a specially crafted DTLS
message, can cause a denial of service. (CVE-2014-3571)

- 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. (CVE-2014-3572)

- A use-after-free error exists in the
'process_nested_data' function within
'ext/standard/var_unserializer.re' due to improper
handling of duplicate keys within the serialized
properties of an object. A remote attacker, using a
specially crafted call to the 'unserialize' method, can
exploit this flaw to execute arbitrary code on the
system. (CVE-2014-8142)

- 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. (CVE-2014-8275)

- An out-of-bounds read flaw in file 'cgi_main.c' exists
when nmap is used to process an invalid file that begins
with a hash character (#) but lacks a newline character.
A remote attacker, using a specially crafted PHP file,
can exploit this vulnerability to disclose memory
contents, cause a denial of service, or possibly execute
code. (CVE-2014-9427)

- An out-of-bounds read error exists in the Fine Free File
component that is bundled with PHP. A remote attacker
can exploit this to cause a denial of service condition
or the disclosure of sensitive information.
(CVE-2014-9652)

- A memory corruption issue exists in the Fine Free File
component that is bundled with PHP. A remote attacker
can exploit this to cause an unspecified impact.
(CVE-2014-9653)

- A heap buffer overflow condition exists in PHP in the
enchant_broker_request_dict() function due to improper
validation of user-supplied input. An attacker can
exploit this to cause a denial of service condition or
the execution of arbitrary code. (CVE-2014-9705)

- A security feature bypass vulnerability, known as FREAK
(Factoring attack on RSA-EXPORT Keys), exists due to the
support of weak EXPORT_RSA cipher suites with keys less
than or equal to 512 bits. A man-in-the-middle attacker
may be able to downgrade the SSL/TLS connection to use
EXPORT_RSA cipher suites which can be factored in a
short amount of time, allowing the attacker to intercept
and decrypt the traffic. (CVE-2015-0204)

- 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. (CVE-2015-0205)

- 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.
(CVE-2015-0206)

- A flaw exists in the DTLSv1_listen() function due to
state being preserved in the SSL object from one
invocation to the next. A remote attacker can exploit
this, via crafted DTLS traffic, to cause a segmentation
fault, resulting in a denial of service.
(CVE-2015-0207)

- A flaw exists in the rsa_item_verify() function due to
improper implementation of ASN.1 signature verification.
A remote attacker can exploit this, via an ASN.1
signature using the RSA PSS algorithm and invalid
parameters, to cause a NULL pointer dereference,
resulting in a denial of service. (CVE-2015-0208)

- 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. (CVE-2015-0209)

- A use-after-free memory error exists in the
process_nested_data() function in 'var_unserializer.re'
due to improper handling of duplicate numerical keys
within the serialized properties of an object. A remote
attacker, using a crafted unserialize method call, can
exploit this vulnerability to execute arbitrary code.
(CVE-2015-0231)

- A flaw exists in the exif_process_unicode() function in
'exif.c' that allows freeing an uninitialized pointer. A
remote attacker, using specially crafted EXIF data in a
JPEG image, can exploit this to cause a denial of
service or to execute arbitrary code. (CVE-2015-0232)

- A use-after-free flaw exists in the function
php_date_timezone_initialize_from_hash() within the
'ext/date/php_date.c' script. An attacker can exploit
this to access sensitive information or crash
applications linked to PHP. (CVE-2015-0273)

- A flaw exists in the ssl3_client_hello() function due to
improper validation of a PRNG seed before proceeding
with a handshake, resulting in insufficient entropy and
predictable output. This allows a man-in-the-middle
attacker to defeat cryptographic protection mechanisms
via a brute-force attack, resulting in the disclosure of
sensitive information. (CVE-2015-0285)

- An invalid read error 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.
(CVE-2015-0286)

- 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. (CVE-2015-0287)

- 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. (CVE-2015-0288)

- 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. (CVE-2015-0289)

- A flaw exists with the 'multiblock' feature in the
ssl3_write_bytes() function due to improper handling of
certain non-blocking I/O cases. This allows a remote
attacker to cause failed connections or a segmentation
fault, resulting in a denial of service. (CVE-2015-0290)

- A NULL pointer dereference flaw exists when handling
clients attempting to renegotiate using an invalid
signature algorithm extension. A remote attacker can
exploit this to cause a denial of service.
(CVE-2015-0291)

- An integer underflow condition exists in the
EVP_DecodeUpdate() function due to improper validation
of base64 encoded input when decoding. This allows a
remote attacker, using maliciously crafted base64 data,
to cause a segmentation fault or memory corruption,
resulting in a denial of service or possibly the
execution of arbitrary code. (CVE-2015-0292)

- 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. (CVE-2015-0293)

- A flaw exists in the ssl3_get_client_key_exchange()
function when client authentication and an ephemeral
Diffie-Hellman ciphersuite are enabled. This allows a
remote attacker, via a ClientKeyExchange message with a
length of zero, to cause a denial of service.
(CVE-2015-1787)

- A cross-site request forgery (XSRF) vulnerability exists
due to the lack of a unique token when performing
sensitive actions via HTTP requests. (CVE-2015-2134)

- A use-after-free error exists in the function
phar_rename_archive() in file 'phar_object.c'. A remote
attacker, by attempting to rename a phar archive to an
already existing file name, can exploit this to cause
a denial of service. (CVE-2015-2301)

- A use-after-free error exists related to function
'unserialize', which can allow a remote attacker to
execute arbitrary code. Note that this issue is due to
an incomplete fix for CVE-2014-8142. (CVE-2015-0231)

- A filter bypass vulnerability exists due to a flaw in
the move_uploaded_file() function in which pathnames are
truncated when a NULL byte is encountered. This allows a
remote attacker, via a crafted second argument, to
bypass intended extension restrictions and create files
with unexpected names. (CVE-2015-2348)

- A user-after-free error exists in the
process_nested_data() function. This allows a remote
attacker, via a crafted unserialize call, to dereference
already freed memory, resulting in the execution of
arbitrary code. (CVE-2015-2787)
