The Mozilla Maintenance Service in Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 on Windows allows local users to bypass integrity verification and gain privileges via vectors involving junctions.

A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host.

A vulnerability exists in Trend Micro Maximum Security 2022 (17.7) wherein a low-privileged user can write a known malicious executable to a specific location and in the process of removal and restoral an attacker could replace an original folder with a mount point to an arbitrary location, allowing a escalation of privileges on an affected system.

The Mozilla Updater in Mozilla Firefox before 21.0 on Windows does not properly maintain Mozilla Maintenance Service registry entries in certain situations involving upgrades from older Firefox versions, which allows local users to gain privileges by leveraging write access to a "trusted path."

Multiple untrusted search path vulnerabilities in the (1) full installer and (2) stub installer in Mozilla Firefox before 23.0 on Windows allow local users to gain privileges via a Trojan horse DLL in the default downloads directory.

Windows Installer Elevation of Privilege Vulnerability

Race condition in VIPRE Antivirus Premium 4.0.3272 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute

In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any".

Windows Client Server Run-time Subsystem (CSRSS) Elevation of Privilege Vulnerability

PoD operations on misaligned GFNs T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). The implementation of some of these hypercalls for PoD does not enforce the base page frame number to be suitably aligned for the specified order, yet some code involved in PoD handling actually makes such an assumption. These operations are XENMEM_decrease_reservation (CVE-2021-28704) and XENMEM_populate_physmap (CVE-2021-28707), the latter usable only by domains controlling the guest, i.e. a de-privileged qemu or a stub domain. (Patch 1, combining the fix to both these two issues.) In addition handling of XENMEM_decrease_reservation can also trigger a host crash when the specified page order is neither 4k nor 2M nor 1G (CVE-2021-28708, patch 2).

Untrusted search path vulnerability in the installer in Mozilla Firefox before 17.0 and Firefox ESR 10.x before 10.0.11 on Windows allows local users to gain privileges via a Trojan horse DLL in the default downloads directory.

A uncontrolled search path element issue was discovered in Vyaire Medical CareFusion Upgrade Utility used with Windows XP systems, Versions 2.0.2.2 and prior versions. A successful exploit of this vulnerability requires the local user to install a crafted DLL on the target machine. The application loads the DLL and gives the attacker access at the same privilege level as the application.

Untrusted search path vulnerability in the installer in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, and Thunderbird ESR 10.x before 10.0.7 on Windows allows local users to gain privileges via a Trojan horse executable file in a root directory.

xcfa before 5.0.1 creates temporary files insecurely which could allow local users to launch a symlink attack and overwrite arbitrary files. Note: A different vulnerability than CVE-2014-5254.

Xenstore: Guests can get access to Xenstore nodes of deleted domains Access rights of Xenstore nodes are per domid. When a domain is gone, there might be Xenstore nodes left with access rights containing the domid of the removed domain. This is normally no problem, as those access right entries will be corrected when such a node is written later. There is a small time window when a new domain is created, where the access rights of a past domain with the same domid as the new one will be regarded to be still valid, leading to the new domain being able to get access to a node which was meant to be accessible by the removed domain. For this to happen another domain needs to write the node before the newly created domain is being introduced to Xenstore by dom0.

A logged in user may elevate its permissions by abusing a Time-of-Check to Time-of-Use (TOCTOU) race condition. When a particular process flow is initiated, an attacker can exploit this condition to gain unauthorized elevated privileges on the affected system.

An Out-of-Bounds access vulnerability in Trend Micro Apex One could allow a local attacker to create a specially crafted message to cause memory corruption on a certain service process which could lead to local privilege escalation on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

NVIDIA GPU Display Driver for Windows contains a vulnerability where a regular user can cause an out-of-bounds read, which may lead to code execution, denial of service, escalation of privileges, information disclosure, or data tampering.

The Netskope client service (prior to R96) on Windows runs as NT AUTHORITY\SYSTEM which writes log files to a writable directory (C:\Users\Public\netSkope) for a standard user. The files are created and written with a SYSTEM account except one file (logplaceholder) which inherits permission giving all users full access control list. Netskope client restricts access to this file by allowing only read permissions as a standard user. Whenever the Netskope client service restarts, it deletes the logplaceholder and recreates, creating a race condition, which can be exploited by a malicious local user to create the file and set ACL permissions on the file. Once the file is created by a malicious user with proper ACL permissions, all files within C:\Users\Public\netSkope\ becomes modifiable by the unprivileged user. By using Windows pseudo-symlink, these files can be pointed to other places in the system and thus malicious users will be able to elevate privileges.

A Time-of-Check Time-Of-Use vulnerability in the Trend Micro Apex One Vulnerability Protection integrated component could allow a local attacker to escalate privileges and turn a specific working directory into a mount point on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

Windows Win32k Elevation of Privilege Vulnerability

Windows Bind Filter Driver Elevation of Privilege Vulnerability

Microsoft Brokering File System Elevation of Privilege Vulnerability

In the Linux kernel, the following vulnerability has been resolved: ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs The dreamcastcard->timer could schedule the spu_dma_work and the spu_dma_work could also arm the dreamcastcard->timer. When the snd_pcm_substream is closing, the aica_channel will be deallocated. But it could still be dereferenced in the worker thread. The reason is that del_timer() will return directly regardless of whether the timer handler is running or not and the worker could be rescheduled in the timer handler. As a result, the UAF bug will happen. The racy situation is shown below: (Thread 1) | (Thread 2) snd_aicapcm_pcm_close() | ... | run_spu_dma() //worker | mod_timer() flush_work() | del_timer() | aica_period_elapsed() //timer kfree(dreamcastcard->channel) | schedule_work() | run_spu_dma() //worker ... | dreamcastcard->channel-> //USE In order to mitigate this bug and other possible corner cases, call mod_timer() conditionally in run_spu_dma(), then implement PCM sync_stop op to cancel both the timer and worker. The sync_stop op will be called from PCM core appropriately when needed.

Windows Update Stack Elevation of Privilege Vulnerability

Race condition in the thread-creation implementation in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP3 allows local users to gain privileges via a crafted application, aka "Win32k.sys Race Condition Vulnerability."
