Esg version 2.5 suffers from a cross site scripting vulnerability.

This exploit takes advantage of a vulnerability in sudoedit, part of the sudo package. The sudoedit (aka sudo -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. by appending extra entries on /etc/sudoers allowing for execution of an arbitrary payload with root privileges. Affected versions are 1.8.0 through 1.9.12.p1. However, this module only works against Ubuntu 22.04 and 22.10. This module was tested against sudo 1.9.9-1ubuntu2 on Ubuntu 22.04 and 1.9.11p3-1ubuntu1 on Ubuntu 22.10.

Ubuntu Security Notice 5725-2 - USN-5725-1 fixed a vulnerability in Go. This update provides the corresponding update for Ubuntu 16.04 LTS. Diederik Loerakker, Jonny Rhea, Raúl Kripalani, and Preston Van Loon discovered that Go incorrectly handled certain inputs. An attacker could possibly use this issue to cause Go applications to hang or crash, resulting in a denial of service.

Ubuntu Security Notice 6073-9 - USN-6073-4 fixed a vulnerability in os-brick. Unfortunately the update introduced a regression with detaching volumes. The security fix has been removed pending further investigation. Jan Wasilewski and Gorka Eguileor discovered that os-brick incorrectly handled deleted volume attachments. An authenticated user or attacker could possibly use this issue to gain access to sensitive information.

Ubuntu Security Notice 6073-6 - USN-6073-1 fixed a vulnerability in Cinder. Unfortunately the update introduced a regression with detaching volumes. The security fix has been removed pending further investigation. Jan Wasilewski and Gorka Eguileor discovered that Cinder incorrectly handled deleted volume attachments. An authenticated user or attacker could possibly use this issue to gain access to sensitive information.

Ubuntu Security Notice 6073-7 - USN-6073-2 fixed a vulnerability in Glance_store. Unfortunately the update introduced a regression with detaching volumes. The security fix has been removed pending further investigation. Jan Wasilewski and Gorka Eguileor discovered that Glance_store incorrectly handled deleted volume attachments. An authenticated user or attacker could possibly use this issue to gain access to sensitive information.

Ubuntu Security Notice 6073-8 - USN-6073-3 fixed a vulnerability in Nova. Unfortunately the update introduced a regression with detaching volumes. The security fix has been removed pending further investigation. Jan Wasilewski and Gorka Eguileor discovered that Nova incorrectly handled deleted volume attachments. An authenticated user or attacker could possibly use this issue to gain access to sensitive information.

Ubuntu Security Notice 6099-1 - It was discovered that ncurses was incorrectly performing bounds checks when processing invalid hashcodes. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. This issue only affected Ubuntu 18.04 LTS. It was discovered that ncurses was incorrectly handling end-of-string characters when processing terminfo and termcap files. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. This issue only affected Ubuntu 18.04 LTS.

Ubuntu Security Notice 6094-1 - Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service. Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information.

Ubuntu Security Notice 6096-1 - It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service.
