MS15-014: Vulnerability in Group Policy Could Allow Security Feature Bypass (3004361)

The version of Windows running on the remote host is affected by a security downgrade vulnerability that affects workstations and servers configured to use Group Policy. A man-in-the-middle attacker, via modified domain controller responses sent to targeted systems, can cause the policy file to...

openssl: TLS protocol downgrade attack

A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions...

openssl: ECDH downgrade bug fix

It was discovered that OpenSSL would perform an ECDH key exchange with a non-ephemeral key even when the ephemeral ECDH cipher suite was selected. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method than the one requested by the user...

Oracle Solaris Third-Party Patch Update : openssl (cve_2014_3508_information_disclosure)

The remote Solaris system is missing necessary patches to address security updates : - The OBJobj2txt function in crypto/objects/objdat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of '\0' characters,...

OpenSSL 0.9.8 < 0.9.8zd Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 0.9.8zd. It is, therefore, affected by multiple vulnerabilities as referenced in the 0.9.8zd advisory. - The BNsqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the...

OpenSSL 1.0.0 < 1.0.0p Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.0p. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.0p advisory. - Memory leak in the dtls1bufferrecord function in d1pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allows remote...

OpenSSL RSA Temporary Key Cryptographic Downgrade Vulnerability

A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to bypass security restrictions. The vulnerability is due to improper handling of an RSA temporary key. An attacker with a privileged network position could exploit the vulnerability by returning a weak temporary RSA key t...

Amazon Linux AMI : openssl (ALAS-2015-469) (FREAK)

OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service NULL pointer dereference and application crash via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake bod...

USN-2459-1 openssl vulnerabilities

Pieter Wuille discovered that OpenSSL incorrectly handled Bignum squaring. CVE-2014-3570 Markus Stenberg discovered that OpenSSL incorrectly handled certain crafted DTLS messages. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. CVE-2014-3571...

Debian DSA-3125-1 : openssl - security update (FREAK)

Multiple vulnerabilities have been discovered in OpenSSL, a Secure Sockets Layer toolkit. The Common Vulnerabilities and Exposures project identifies the following issues : - CVE-2014-3569 Frank Schmirler reported that the ssl23getclienthello function in OpenSSL does not properly handle attempts ...
