PCI devices with RMRRs not deassigned correctly Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory Region Reporting, "RMRR"). These are typically used for platform tasks such as legacy USB emulation. If such a device is passed through to a guest, then on guest shutdown the device is not properly deassigned. The IOMMU configuration for these devices which are not properly deassigned ends up pointing to a freed data structure, including the IO Pagetables. Subsequent DMA or interrupts from the device will have unpredictable behaviour, ranging from IOMMU faults to memory corruption.
certain VT-d IOMMUs may not work in shared page table mode For efficiency reasons, address translation control structures (page tables) may (and, on suitable hardware, by default will) be shared between CPUs, for second-level translation (EPT), and IOMMUs. These page tables are presently set up to always be 4 levels deep. However, an IOMMU may require the use of just 3 page table levels. In such a configuration the lop level table needs to be stripped before inserting the root table's address into the hardware pagetable base register. When sharing page tables, Xen erroneously skipped this stripping. Consequently, the guest is able to write to leaf page table entries.
Jupyter Core is a package for the core common functionality of Jupyter projects. Jupyter Core prior to version 4.11.2 contains an arbitrary code execution vulnerability in `jupyter_core` that stems from `jupyter_core` executing untrusted files in CWD. This vulnerability allows one user to run code as another. Version 4.11.2 contains a patch for this issue. There are no known workarounds.
Nextcloud Server is a self hosted personal cloud system. When a server is configured to only allow sharing with users that are in ones own groups, after a user was removed from a group, previously shared items were not unshared. It is recommended that the Nextcloud Server is upgraded to 22.2.11 or 23.0.11 or 24.0.6 and Nextcloud Enterprise Server is upgraded to 22.2.11 or 23.0.11 or 24.0.6.
multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.
Nextcloud files access control is a nextcloud app to manage access control for files. Users with limited access can see file names in certain cases where they do not have privilege to do so. This issue has been addressed and it is recommended that the Nextcloud Files Access Control app is upgraded to 1.12.2, 1.13.1 or 1.14.1. There are no known workarounds for this issue
gksu-polkit: permissive PolicyKit policy configuration file allows privilege escalation
A flaw was found in cifs-utils in versions before 6.13. A user when mounting a krb5 CIFS file system from within a container can use Kerberos credentials of the host. The highest threat from this vulnerability is to data confidentiality and integrity.
IBM Spectrum Copy Data Management 2.2.0.0 through 2.2.15.0 is vulnerable to reverse tabnabbing where it could allow a page linked to from within IBM Spectrum Copy Data Management to rewrite it. An administrator could enter a link to a malicious URL that another administrator could then click. Once clicked, that malicious URL could then rewrite the original page with a phishing page. IBM X-Force ID: 227363.
Thunderbird unexpectedly enabled JavaScript in the composition area. The JavaScript execution context was limited to this area and did not receive chrome-level privileges, but could be used as a stepping stone to further an attack with other vulnerabilities. This vulnerability affects Thunderbird < 91.4.0.
Bhima version 1.27.0 allows a remote attacker to update the privileges of any account registered in the application via a malicious link sent to an administrator. This is possible because the application is vulnerable to CSRF.
Orbit Fox by ThemeIsle has a feature to add a registration form to both the Elementor and Beaver Builder page builders functionality. As part of the registration form, administrators can choose which role to set as the default for users upon registration. This field is hidden from view for lower-level users, however, they can still supply the user_role parameter to update the default role for registration.
An elevation of privilege vulnerability exists in Microsoft Azure Active Directory Connect build 1.3.20.0, which allows an attacker to execute two PowerShell cmdlets in context of a privileged account, and perform privileged actions.To exploit this, an attacker would need to authenticate to the Azure AD Connect server, aka 'Microsoft Azure AD Connect Elevation of Privilege Vulnerability'.
