Red Hat Security Advisory 2016-0371-01 – Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. A heap-based buffer overflow flaw was found in the way NSS parsed certain ASN.1 structures. An attacker could use this flaw to create a specially crafted certificate which, when parsed by NSS, could cause it to crash, or execute arbitrary code, using the permissions of the user running an application compiled against the NSS library.

Red Hat Security Advisory 2016-0373-01 – Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. Multiple security flaws were found in the graphite2 font library shipped with Firefox. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox.

Gentoo Linux Security Advisory 201603-3 – Multiple vulnerabilities have been found in Roundcube allowing remote authenticated users to execute arbitrary code, inject arbitrary web scripts, and perform cross-site scripting (XSS). Versions less than 1.1.4 are affected.

Red Hat Security Advisory 2016-0367-01 – RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is a robust and scalable implementation of an AMQP broker. A cross-site scripting vulnerability was discovered in RabbitMQ, which allowed using api/ path info to inject and receive data. A remote attacker could use this flaw to create an “/api/…” URL, forcing a server error that resulted in the server returning an HTML page with embedded text from the URL. A response-splitting vulnerability was discovered in RabbitMQ. An /api/definitions URL could be specified, which then caused an arbitrary additional header to be returned. A remote attacker could use this flaw to inject arbitrary HTTP headers and possibly gain access to secure data.

Red Hat Security Advisory 2016-0370-01 – Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. The nss-util package provides a set of utilities for NSS and the Softoken module. A heap-based buffer overflow flaw was found in the way NSS parsed certain ASN.1 structures. An attacker could use this flaw to create a specially crafted certificate which, when parsed by NSS, could cause it to crash, or execute arbitrary code, using the permissions of the user running an application compiled against the NSS library.

Red Hat Security Advisory 2016-0372-01 – OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. A padding oracle flaw was found in the Secure Sockets Layer version 2.0 protocol. An attacker can 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 is publicly referred to as DROWN.
