In its latest Windows preview, Microsoft adds a feature — Administrator Protection — designed to prevent threat actors from easily escalating privileges and restrict lateral movement.

Rather than setting a regular cadence for changing passwords, users only need to change their passwords if there is evidence of a breach.

### Impact The btcd Bitcoin client (versions 0.10 to 0.24) did not correctly re-implement Bitcoin Core's "FindAndDelete()" functionality. This logic is consensus-critical: the difference in behavior with the other Bitcoin clients can lead to btcd clients accepting an invalid Bitcoin block (or rejecting a valid one). This consensus failure can be leveraged to cause a chain split (accepting an invalid Bitcoin block) or be exploited to DoS the btcd nodes (rejecting a valid Bitcoin block). An attacker can create a standard transaction where FindAndDelete doesn't return a match but removeOpCodeByData does making btcd get a different sighash, leading to a chain split. Importantly, this vulnerability can be exploited remotely by any Bitcoin user and does not require any hash power. This is because the difference in behavior can be triggered by a "standard" Bitcoin transaction, that is a transaction which gets relayed through the P2P network before it gets included in a Bitcoin block. ####...

The BMS/BAS controller has a directory traversal vulnerability that can be exploited by an unauthenticated attacker to list the contents of arbitrary directories without reading file contents, leading to information disclosure of directory structures and filenames. This may expose sensitive system details, aiding in further attacks. The issue lies in the listFiles() function of the persistenceManagerAjax.php script, which calls PHP's readdir() function without proper input validation of the 'directory' POST parameter.

ABB Cylon Aspect version 3.08.01 has a directory traversal vulnerability that can be exploited by an unauthenticated attacker to list the contents of arbitrary directories without reading file contents, leading to information disclosure of directory structures and filenames. This may expose sensitive system details, aiding in further attacks. The issue lies in the listFiles() function of the persistenceManagerAjax.php script, which calls PHP's readdir() function without proper input validation of the directory POST parameter.

Palo Alto Networks GlobalProtect versions 5.1.x, 5.2.x, 6.0.x, 6.1.x, 6.3.x and versions less than 6.2.5 suffer from a local privilege escalation vulnerability.

Ubuntu Security Notice 7061-1 - Hunter Wittenborn discovered that Go incorrectly handled the sanitization of environment variables. An attacker could possibly use this issue to run arbitrary commands. Sohom Datta discovered that Go did not properly validate backticks as Javascript string delimiters, and did not escape them as expected. An attacker could possibly use this issue to inject arbitrary Javascript code into the Go template.

Ubuntu Security Notice 7022-3 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7060-1 - It was discovered that EDK II did not check the buffer length in XHCI, which could lead to a stack overflow. A local attacker could potentially use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Laszlo Ersek discovered that EDK II incorrectly handled recursion. A remote attacker could possibly use this issue to cause EDK II to consume resources, leading to a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Ubuntu Security Notice 7059-1 - Fabian Vogt discovered that OATH Toolkit incorrectly handled file permissions. A remote attacker could possibly use this issue to overwrite root owned files, leading to a privilege escalation attack.
