Forcepoint Web Security Content Gateway versions prior to 8.5.4 improperly process XML input, leading to information disclosure.

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verific…

Path Traversal vulnerability in McAfee McAfee Email Gateway (MEG) prior to 7.6.406 allows remote attackers to traverse the file system to access files or directories that are outside of the restricted directory via external input to construct a path name that should be within a restricted directory.

An authentication weakness vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow an attacker to recover user passwords on vulnerable installations due to a flaw in the DBCrypto class. An attacker must first obtain access to the user database on the target system in order to exploit this vulnerability.

A SQL injection information disclosure vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow a remote attacker to disclose sensitive information on vulnerable installations due to a flaw in the formChangePass class. Authentication is required to exploit this vulnerability.

A vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow a remote attacker to execute arbitrary SQL statements on vulnerable installations due to a flaw in the formRegistration2 class. Authentication is required to exploit this vulnerability.

A command injection remote command execution vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow a remote attacker to execute arbitrary code on vulnerable installations due to a flaw in the LauncherServer. Authentication is required to exploit this vulnerability.

A SQL injection remote code execution vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow an attacker to execute arbitrary SQL statements on vulnerable installations due to a flaw in the formRequestDomains class. Authentication is required to exploit this vulnerability.

A vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow a remote attacker to execute arbitrary SQL statements on vulnerable installations due to a flaw in the formConfiguration class. Authentication is required to exploit this vulnerability.

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.
