It was discovered that the Unitrends bpserverd proprietary protocol, as exposed via xinetd, has an issue in which its authentication can be bypassed. A remote attacker could use this issue to execute arbitrary commands with root privilege on the target system.

The login component of the Polycom Command Shell on Polycom HDX video endpoints, running software versions 3.0.5 and earlier, is vulnerable to an authorization bypass when simultaneous connections are made to the service, allowing remote network attackers to gain access to a sandboxed telnet prompt without authentication. Versions prior to 3.0.4 contain OS command injection in the ping command which can be used to execute arbitrary commands as root.

Numerous remote code execution paths were discovered in TP-Link's WR940N home WiFi router. Valid credentials are required for this attack path. It is possible for an authenticated attacker to obtain a remote shell with root privileges.

ZKTime Web Software version 2.0 suffers from a cross site request forgery vulnerability.

Red Hat Security Advisory 2017-2998-01 - The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. Security Fix: Multiple flaws were discovered in the RMI and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions. It was discovered that the Kerberos client implementation in the Libraries component of OpenJDK used the sname field from the plain text part rather than encrypted part of the KDC reply message. A man-in-the-middle attacker could possibly use this flaw to impersonate Kerberos services to Java applications acting as Kerberos clients.

Red Hat Security Advisory 2017-2997-01 - Chromium is an open-source web browser, powered by WebKit. This update upgrades Chromium to version 62.0.3202.62. Security Fix: Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to crash, execute arbitrary code, or disclose sensitive information when visited by the victim.

Debian Linux Security Advisory 4003-1 - Daniel P. Berrange reported that Libvirt, a virtualisation abstraction library, does not properly handle the default_tls_x509_verify (and related) parameters in qemu.conf when setting up TLS clients and servers in QEMU, resulting in TLS clients for character devices and disk devices having verification turned off and ignoring any errors while validating the server certificate.

Debian Linux Security Advisory 4002-1 - Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to the new upstream version 5.5.58, which includes additional changes, such as performance improvements, bug fixes, new features, and possibly incompatible changes. Please see the MySQL 5.5 Release Notes and Oracle's Critical Patch Update advisory for further details.

Mozilla Firefox versions prior to 55 suffer from a long username denial of service vulnerability.

Check_mk versions 1.2.8p25 and below suffer from a save_users() race condition that leads to sensitive information disclosure.

Red Hat Security Advisory 2017-2972-01 - The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. Security Fix: A use-after-free flaw was found in the way httpd handled invalid and previously unregistered HTTP methods specified in the Limit directive used in an .htaccess file. A remote attacker could possibly use this flaw to disclose portions of the server memory, or cause httpd child process to crash.

Red Hat Security Advisory 2017-2966-01 - Ansible is a simple model-driven configuration management, multi-node deployment, and remote-task execution system. Ansible works over SSH and does not require any software or daemons to be installed on remote nodes. Extension modules can be written in any language and are transferred to managed machines automatically. The ansible packages have been upgraded to upstream version 2.4.0, which provides a number of bug fixes and enhancements over the previous version. For more information, please see the Ansible 2.4 Porting Guide linked in the References section.

Red Hat Security Advisory 2017-2931-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket could use this flaw to elevate their privileges on the system.

Red Hat Security Advisory 2017-2930-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket could use this flaw to elevate their privileges on the system.

BMC Remedy suffers from log hijacking, code execution, cross site scripting, local/remote file inclusion, and various other vulnerabilities.

FreeBSD Security Advisory - A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

Red Hat Security Advisory 2017-2918-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization.
