OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS. This directory is most commonly referred to as OPENSSLDIR, and is configurable with the --prefix / --openssldir configuration options. For OpenSSL versions 1.1.0 and 1.1.1, the mingw configuration targets assume that resulting programs and libraries are installed in a Unix-like environment and the default prefix for program installation as well as for OPENSSLDIR should be '/usr/local'. However, mingw programs are Windows programs, and as such, find themselves looking at sub-directories of 'C:/usr/local', which may be world writable, which enables untrusted users to modify OpenSSL's default configuration, insert CA certificates, modify (or even replace) existing engine modules, etc. For OpenSSL 1.0.2, '/usr/local/ssl' is used as default for OPENSSLDIR on all Unix and Windows targets, including Visual C builds. However, some build instructions for the diverse Windows targets on 1.0.2 encourage you to specify your own --prefix. OpenSSL versions 1.1.1, 1.1.0 and 1.0.2 are affected by this issue. Due to the limited scope of affected deployments this has been assessed as low severity and therefore we are not creating new releases at this time. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).

  - An integer overflow was found in the x64_64 Montgomery     squaring procedure used in exponentiation with 512-bit     moduli. As per upstream: * No EC algorithms are     affected. * Attacks against 2-prime RSA1024, 3-prime     RSA1536, and DSA1024 as a result of this defect would     be very difficult to perform and are not believed     likely. * Attacks against DH512 are considered just     feasible. However, for an attack the target would have     to re-use the DH512 private key, which is not     recommended anyway. * Also applications directly using     the low level API BN_mod_exp may be affected if they     use BN_FLG_CONSTTIME(CVE-2019-1551)

According to the versions of the openssl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - In situations where an attacker receives automated     notification of the success or failure of a decryption     attempt an attacker, after sending a very large number     of messages to be decrypted, can recover a CMS/PKCS7     transported encryption key or decrypt any RSA encrypted     message that was encrypted with the public RSA key,     using a Bleichenbacher padding oracle attack.
    Applications are not affected if they use a certificate     together with the private RSA key to the CMS_decrypt or     PKCS7_decrypt functions to select the correct recipient     info to decrypt.

  - Normally in OpenSSL EC groups always have a co-factor     present and this is used in side channel resistant code     paths. However, in some cases, it is possible to     construct a group using explicit parameters (instead of     using a named curve). In those cases it is possible     that such a group does not have the cofactor present.
    This can occur even where all the parameters match a     known named curve. If such a curve is used then OpenSSL     falls back to non-side channel resistant code paths     which may result in full key recovery during an ECDSA     signature operation. In order to be vulnerable an     attacker would have to have the ability to time the     creation of a large number of signatures where explicit     parameters with no co-factor present are in use by an     application using libcrypto. For the avoidance of doubt     libssl is not vulnerable because explicit parameters     are never used. Fixed in OpenSSL 1.1.1d (Affected     1.1.1-1.1.1c).

The version of Oracle Secure Global Desktop installed on the remote host is missing a security patch from the January 2020 Critical Patch Update (CPU). It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability exists in the Core (Apache Axis) component. An unauthenticated,     adjacent attacker can exploit this issue, to execute arbitrary commands. (CVE-2019-0227)

  - A cross-site scripting vulnerability exists in the Web Server (Appache HTTPD Server) component. An     unauthenticated, remote attacker can exploit this issue via causing the link on the mod_proxy error page     to be malformed and point to a page of the attacker's choice. (CVE-2019-10092)

  - A cross-site scripting vulnerability exists in faces/context/PartialViewContextImpl.java in Eclipse     (Mojarra) due to mishandling of a client window field. An unauthenticated, remote attacker can exploit     this issue, to perform unauthorized update, insert or delete access to some of Oracle Communications     Unified Inventory Management accessible data as well as to perform an unauthorized read access to a subset     of Oracle Communications Unified Inventory Management accessible data.

  - OpenSSL 1.1.1 introduced a rewritten random number     generator (RNG). This was intended to include     protection in the event of a fork() system call in     order to ensure that the parent and child processes did     not share the same RNG state. However this protection     was not being used in the default case. A partial     mitigation for this issue is that the output from a     high precision timer is mixed into the RNG state so the     likelihood of a parent and child process sharing state     is significantly reduced. If an application already     calls OPENSSL_init_crypto() explicitly using     OPENSSL_INIT_ATFORK then this problem does not occur at     all.

According to the versions of the openssl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Normally in OpenSSL EC groups always have a co-factor     present and this is used in side channel resistant code     paths. However, in some cases, it is possible to     construct a group using explicit parameters (instead of     using a named curve). In those cases it is possible     that such a group does not have the cofactor present.
    This can occur even where all the parameters match a     known named curve. If such a curve is used then OpenSSL     falls back to non-side channel resistant code paths     which may result in full key recovery during an ECDSA     signature operation. In order to be vulnerable an     attacker would have to have the ability to time the     creation of a large number of signatures where explicit     parameters with no co-factor present are in use by an     application using libcrypto. For the avoidance of doubt     libssl is not vulnerable because explicit parameters     are never used. (CVE-2019-1547)

  - In situations where an attacker receives automated     notification of the success or failure of a decryption     attempt an attacker, after sending a very large number     of messages to be decrypted, can recover a CMS/PKCS7     transported encryption key or decrypt any RSA encrypted     message that was encrypted with the public RSA key,     using a Bleichenbacher padding oracle attack.
    Applications are not affected if they use a certificate     together with the private RSA key to the CMS_decrypt or     PKCS7_decrypt functions to select the correct recipient     info to decrypt.(CVE-2019-1563)

  - OpenSSL 1.1.1 introduced a rewritten random number     generator (RNG). This was intended to include     protection in the event of a fork() system call in     order to ensure that the parent and child processes did     not share the same RNG state. However this protection     was not being used in the default case. A partial     mitigation for this issue is that the output from a     high precision timer is mixed into the RNG state so the     likelihood of a parent and child process sharing state     is significantly reduced. If an application already     calls OPENSSL_init_crypto() explicitly using     OPENSSL_INIT_ATFORK then this problem does not occur at     all.(CVE-2019-1549)

  - OpenSSL has internal defaults for a directory tree     where it can find a configuration file as well as     certificates used for verification in TLS.

According to the versions of the openssl110h packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - ChaCha20-Poly1305 is an AEAD cipher, and requires a     unique nonce input for every encryption operation. RFC     7539 specifies that the nonce value (IV) should be 96     bits (12 bytes). OpenSSL allows a variable nonce length     and front pads the nonce with 0 bytes if it is less     than 12 bytes. However it also incorrectly allows a     nonce to be set of up to 16 bytes. In this case only     the last 12 bytes are significant and any additional     leading bytes are ignored. It is a requirement of using     this cipher that nonce values are unique. Messages     encrypted using a reused nonce value are susceptible to     serious confidentiality and integrity attacks. If an     application changes the default nonce length to be     longer than 12 bytes and then makes a change to the     leading bytes of the nonce expecting the new value to     be a new unique nonce then such an application could     inadvertently encrypt messages with a reused nonce.
    Additionally the ignored bytes in a long nonce are not     covered by the integrity guarantee of this cipher. Any     application that relies on the integrity of these     ignored leading bytes of a long nonce may be further     affected. Any OpenSSL internal use of this cipher,     including in SSL/TLS, is safe because no such use sets     such a long nonce value. However user applications that     use this cipher directly and set a non-default nonce     length to be longer than 12 bytes may be vulnerable.
    OpenSSL versions 1.1.1 and 1.1.0 are affected by this     issue. Due to the limited scope of affected deployments     this has been assessed as low severity and therefore we     are not creating new releases at this     time.(CVE-2019-1543)
