| An elevation of privilege vulnerability exists when the Windows Cryptography Next Generation (CNG) Key Isolation service improperly handles memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.
To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges.
The security update addresses the vulnerability by correcting how the Windows CNG Key Isolation Service handles memory. |
| Affected versions of Git have a heap buffer overflow in the three-way merge
code (xdiff), which an attacker can trigger through a repository they
control.
When Git merges a file, it first adds up the size of the merged
output, allocates a buffer of that size, and then writes the output into
it. That total was kept in a 32-bit signed integer. The
conflict-marker-size attribute, which can be set from a committed
.gitattributes file, accepts any positive integer, and the markers are
written several times for every conflict. A small file with a huge marker
size and many separate conflicts can therefore push the total past 4 GiB,
so the integer wraps to a small value and Git writes attacker-controlled
merge output past the end of a buffer that is too small. At minimum this
crashes Git, and because the overflow is large and its contents are largely
attacker-controlled, worse heap corruption is possible.
Any command that does a textual three-way merge can trigger it, such
as git-merge(1), git-rebase(1), git-cherry-pick(1), and
git-merge-tree(1). The latter is most likely a target for Git forges,
which might use git-merge-tree(1) on the server-side to check
mergeability. When the server reads attributes from trees in the
repository (for example through attr.tree or --attr-source), any
user who can push branches and request that they be merged (for
example by opening a pull or merge request) can trigger the overflow
without anyone else doing anything, and the data they push is small
because the oversized output only appears during the merge.
The problem has been patched by computing the size as size_t and
checking every addition for overflow, so Git stops with an error
instead of overflowing.
Servers that cannot upgrade right away can add
* conflict-marker-size=7
to each repository's info/attributes as a workaround, which overrides
any in-tree .gitattributes, or turn off server-side mergeability checks for
untrusted repositories. |
| In event_set_sub of acropora_event.c, there is a possible Logic error due to a logic error in the code. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation. |
| In handle_rx_msg of tipc_virtio_dev, there is a possible Double Fetch TOCTOU due to Double Fetch. This could lead to local information disclosure with execution privileges needed. User interaction is for exploitation. |
| Premiere Pro is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| Operation on a resource after expiration or release in the AMD Secure Encrypted Virtualization (SEV) firmware could allow an attacker with administrative privileges to swap out a guest device without the guest's knowledge, potentially resulting in a loss of confidentiality and integrity. |
| Heap-based buffer overflow in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally. |
| Stack-based buffer overflow in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally. |
| Double free in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally. |
| Out-of-bounds read in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Management Instrumentation allows an authorized attacker to elevate privileges locally. |
| An elevation of privilege vulnerability exists in the way that the Windows Kernel handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.
The security update addresses the vulnerability by ensuring the Windows Kernel properly handles objects in memory. |
| Relative path traversal in Microsoft Input Method Editor (IME) allows an authorized attacker to elevate privileges locally. |
| Buffer over-read in Windows Shell allows an authorized attacker to disclose information locally. |
| An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior.
A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. |

| Buffer over-read in Windows Message Queuing allows an unauthorized attacker to deny service over a network. |
| Improper link resolution before file access ('link following') in Windows DNS allows an authorized attacker to elevate privileges over a network. |
