We hope you enjoyed the first day of our BlueHat briefings and the Bytes of BlueHat reception in our glamping tent (complete with toasted marshmallows). Yesterday, we learned a lot about how XboxOne hardware security has advanced the state of hardware security elsewhere, we heard some surprising correlations between vuln severity, age, and time to fix, and we saw applications for machine learning for malware detection—as well as some of the attack surface for machine learning and how to protect it.

An exploitable privilege escalation vulnerability exists in the Wacom, driver version 6.3.32-3, update helper service in the start/stopLaunchDProcess command. The command takes a user-supplied string argument and executes launchctl under root context. A user with local access can use this vulnerability to raise load arbitrary launchD agents. An attacker would need local access to the machine for a successful exploit.

An exploitable privilege escalation vulnerability exists in the Wacom, driver version 6.3.32-3, update helper service in the startProcess command. The command takes a user-supplied script argument and executes it under root context. A user with local access can use this vulnerability to raise their privileges to root. An attacker would need local access to the machine for a successful exploit.

We’ve finished two incredible days of security trainings at the Living Computer Museum in Seattle. Now it’s time for the second part of BlueHat: the briefings at ShowBox SoDo. We’ve got a big day planned, so head on down. Please join us for breakfast (we have doughnuts! and bacon! and cereal!

A Local Privilege Escalation vulnerability exists in GlobalProtect Agent for Linux and Mac OS X version 5.0.4 and earlier and version 4.1.12 and earlier, that can allow non-root users to overwrite root files on the file system.

A Local Privilege Escalation vulnerability exists in the GlobalProtect Agent for Windows 5.0.3 and earlier, and GlobalProtect Agent for Windows 4.1.12 and earlier, in which the auto-update feature can allow for modification of a GlobalProtect Agent MSI installer package on disk before installation.

Vulnerability in the Java SE product of Oracle Java SE (component: Javadoc). Supported versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE accessible data as well as unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Ja...

An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges because a guest can manipulate its virtualised %cr4 in a way that is incompatible with Linux (and possibly other guest kernels).

An exploitable memory corruption vulnerability exists in the JavaScript engine of Foxit Software's Foxit PDF Reader, version 9.4.1.16828. A specially crafted PDF document can trigger an out-of-memory condition which isn't handled properly, resulting in arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.

An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow.
