CUPS 1.4.4, when running in certain Linux distributions such as Debian GNU/Linux, stores the web interface administrator key in /var/run/cups/certs/0 using certain permissions, which allows local users in the lpadmin group to read or write arbitrary files as root by leveraging the web interface.

An exploitable privilege escalation vulnerability exists in the Wacom, driver version 6.3.32-3, update helper service in the startProcess command. The command takes a user-supplied script argument and executes it under root context. A user with local access can use this vulnerability to raise their privileges to root. An attacker would need local access to the machine for a successful exploit.

ESXi, Workstation, Fusion, VMRC and Horizon Client contain a use-after-free vulnerability in the virtual sound device. VMware has evaluated the severity of this issue to be in the Important severity range with a maximum CVSSv3 base score of 8.5.

EMC Avamar Client 4.x, 5.x, and 6.x on HP-UX and Mac OS X, and the EMC Avamar plugin 4.x, 5.x, and 6.x for Oracle, uses world-writable permissions for cache directories, which allows local users to gain privileges via an unspecified symlink attack.

Use-after-free vulnerability in IOSurface in Apple OS X before 10.11.6 allows local users to gain privileges via unspecified vectors.

A logic issue was addressed with improved state management. This issue is fixed in tvOS 14.6, Security Update 2021-004 Mojave, iOS 14.6 and iPadOS 14.6, Security Update 2021-003 Catalina, macOS Big Sur 11.4, watchOS 7.5. An application may be able to execute arbitrary code with kernel privileges.

Multiple out-of-bounds write issues were addressed with improved bounds checking. This issue is fixed in macOS Big Sur 11.6.1. A malicious application may be able to execute arbitrary code with kernel privileges.

In ksh version 20120801, a flaw was found in the way it evaluates certain environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. Services and applications that allow remote unauthenticated attackers to provide one of those environment variables could allow them to exploit this issue remotely.

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for macOS could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The openvpn_launcher binary is setuid root. This program is called during the connection process and executes several operating system utilities to configure the system. The networksetup utility is called using relative paths. A local unprivileged user can execute arbitrary commands as root by creating a networksetup trojan which will be executed during the connection process. This is possible because the PATH environment variable is not reset prior to executing the OS utility.

The queueing primitives in IOMobileFrameBuffer in Apple iOS before 4.2.9 and 4.3.x before 4.3.4 do not properly perform type conversion, which allows local users to gain privileges via a crafted application.

The i386_set_ldt system call in the kernel in Apple Mac OS X before 10.6.7 does not properly handle call gates, which allows local users to gain privileges via vectors involving the creation of a call gate entry.

vmware-mount in VMware Workstation 7.x before 7.1.2 build 301548 on Linux, VMware Player 3.1.x before 3.1.2 build 301548 on Linux, VMware Server 2.0.2 on Linux, and VMware Fusion 3.1.x before 3.1.2 build 332101 does not properly load libraries, which allows host OS users to gain privileges via vectors involving shared object files.

The IOUSBDeviceFamily driver in the USB implementation in the kernel in Apple iOS before 6.1.3 and Apple TV before 5.2.1 accesses pipe object pointers that originated in userspace, which allows local users to gain privileges via crafted code.

Networking in Apple iOS before 4.2 accesses an invalid pointer during the processing of packet filter rules, which allows local users to gain privileges via unspecified vectors.

The kernel in Apple OS X before 10.11.1 allows local users to gain privileges by leveraging an unspecified "type confusion" during Mach task processing.

The Install Framework Legacy component in Apple OS X before 10.11 allows local users to obtain root privileges via vectors involving a privileged executable file.

A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.

NetAuthSysAgent in Network Authorization in Apple Mac OS X 10.5.8 does not have the expected authorization requirements, which allows local users to gain privileges via unspecified vectors.

The vmx86 kernel extension in VMware Fusion before 2.0.6 build 196839 does not use correct file permissions, which allows host OS users to gain privileges on the host OS via unspecified vectors.

Unspecified vulnerability in the VBoxNetAdpCtl configuration tool in Sun VirtualBox 3.0.x before 3.0.8 on Solaris x86, Linux, and Mac OS X allows local users to gain privileges via unknown vectors.

The svpn and policyserver components of the F5 BIG-IP APM client prior to version 7.1.7.1 for Linux and macOS runs as a privileged process and can allow an unprivileged user to get ownership of files owned by root on the local client host. A malicious local unprivileged user may gain knowledge of sensitive information, manipulate certain data, or assume super-user privileges on the local client host.

A validation issue was addressed with improved logic. This issue is fixed in macOS High Sierra 10.13.5, Security Update 2018-003 Sierra, Security Update 2018-003 El Capitan. An attacker with physical access to a device may be able to elevate privileges.

Heap-based buffer overflow in the Recovery Mode component in Apple iPhone OS before 3.1, and iPhone OS before 3.1.1 for iPod touch, allows local users to bypass the passcode requirement and access arbitrary data via vectors related to "command parsing."

Apple Mac OS X 10.0 through 10.2.8 allows local users with a USB keyboard to gain unauthorized access by holding down the CTRL and C keys when the system is booting, which crashes the init process and leaves the user in a root shell.
