The vulnerability of the OpenSSL library, which allows a hacker to decrypt the transmitted data

The vulnerability of the OpenSSL library lies in the fact that the SSLv2 protocol requires the server to send a message called ServerVerify before establishing a connection. As a result, the client possesses a portion of the RSA public key. Exploiting this vulnerability allows a remote attacker t...

The vulnerability of the OpenSSL library, which allows a hacker to decrypt data

The vulnerability in the getclientmasterkey function of the s2srvr.c file, within the SSLv2 implementation using the OpenSSL library, is related to the improper operation of the protection mechanism against prediction attacks. This mechanism incorrectly re-saves the key data before exporting the...

OpenSSL: SSLv2 doesn't block disabled ciphers

A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks...

openssl: assertion failure in SSLv2 servers

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

Moodle Assignment Plugin Cross-Site Request Forgery Vulnerability

Moodle is a free, open-source e-learning software platform, also known as a course management system, learning management system, or virtual learning environment, developed by Dr. Martin Dougiamas in Australia.Assignment is one of the plug-ins used to develop new types of assignments. A cross-sit...

Moodle Single View Design Vulnerability

Moodle is a free, open-source e-learning software platform, also known as a course management system, learning management system, or virtual learning environment, developed by Dr. Martin Dougiamas of Australia. A security vulnerability exists in Single View in versions 2.8.x prior to Moodle 2.8.1...

Moodle Event Monitor Design Vulnerability

Moodle is a free, open-source e-learning software platform, also known as a course management system, learning management system, or virtual learning environment, developed by Dr. Martin Dougiamas of Australia. A security vulnerability exists in Event Monitor in version 2.8.x prior to Moodle...

Apache Jetspeed Cross-Site Scripting Vulnerability (CNVD-2016-01717)

Jetspeed is the United States Apache Apache Software Foundation of a set of open portal platform and enterprise information portal using Java and XML development. A cross-site scripting vulnerability exists in Jetspeed versions 2.2.0 through 2.2.2, which stems from the program allowing HTML tags ...

openssl: Divide-and-conquer session key recovery in SSLv2

It was discovered that the SSLv2 servers using OpenSSL accepted SSLv2 connection handshakes that indicated non-zero clear key length for non-export cipher suites. An attacker could use this flaw to decrypt recorded SSLv2 sessions with the server by using it as a decryption oracle...

openssl: assertion failure in SSLv2 servers

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled...

openssl: SSLv2 Bleichenbacher protection overwrites wrong bytes for export ciphers

It was discovered that the SSLv2 protocol implementation in OpenSSL did not properly implement the Bleichenbacher protection for export cipher suites. An attacker could use a SSLv2 server using OpenSSL as a Bleichenbacher oracle...

Wireshark Denial of Service Vulnerability (CNVD-2016-01444)

Wireshark is the most popular network protocol parser. A denial-of-service vulnerability exists in Wireshark version 2.0.x prior to 2.0.2, which allows remote attackers to cause a denial of service via a crafted packet...

DEBIAN-CVE-2016-0703

The getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to...
