### Impact Installations of jupyter-lsp running in environments without configured file system access control (on the operating system level), and with jupyter-server instances exposed to non-trusted network are vulnerable to unauthorised access and modification of file system beyond the jupyter root directory. Please note this vulnerability is in the extension and is patched in version 2.2.2 of that extension. This extension has been updated in jupyterlab-lsp version 5.0.2. ### Patches Version 2.2.2 has been patched. ### Workarounds Users of jupyterlab who do not use jupyterlab-lsp can uninstall jupyter-lsp. ### Credits We would like to credit Bary Levy, researcher of pillar.security research team, for the discovery and responsible disclosure of this vulnerability.

This Metasploit module exploits an unauthenticated remote command execution vulnerability in WordPress Backup Migration plugin versions 1.3.7 and below. The vulnerability is exploitable through the Content-Dir header which is sent to the /wp-content/plugins/backup-backup/includes/backup-heart.php endpoint. The exploit makes use of a neat technique called PHP Filter Chaining which allows an attacker to prepend bytes to a string by continuously chaining character encoding conversions. This allows an attacker to prepend a PHP payload to a string which gets evaluated by a require statement, which results in command execution.

Ubuntu Security Notice 6588-1 - Matthias Gerstner discovered that the PAM pam_namespace module incorrectly handled special files when performing directory checks. A local attacker could possibly use this issue to cause PAM to stop responding, resulting in a denial of service.

SpyCamLizard version 1.230 remote denial of service exploit.

Ubuntu Security Notice 6559-1 - It was discovered that ZooKeeper incorrectly handled authorization for the getACL command. A remote attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Damien Diederen discovered that ZooKeeper incorrectly handled authorization if SASL Quorum Peer authentication is enabled. An attacker could possibly use this issue to bypass ZooKeeper's authorization system. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 23.04 and Ubuntu 23.10.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. A buffer over-read exists in the dtls_sha256_update function. This bug allows remote attackers to cause a denial of service (crash) and possibly read sensitive information by sending a malformed packet with an over-large fragment length field, due to servers incorrectly handling malformed packets.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. DTLS servers allow remote attackers to reuse the same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability allows remote attackers to obtain sensitive application (data of connected clients).
