Unexpected code execution via --sysroot, -target, -isysroot, -Wl,-syslibroot, and -x cgo flags in cmd/go

Building a malicious package that uses cgo could cause arbitrary code execution at build time through several compiler and linker flags permitted in "#cgo" directives. Specifically, "--sysroot" in GCC and Clang relocates compiler subprograms, spec files, and CRT startup objects to an attacker-controlled directory; "-target" in Clang falls back to executing target helper tools from the current working directory when not found in PATH; "-isysroot" and "-Wl,-syslibroot" can pass a regular file on disk to GNU ld.bfd, which interprets it as a positional linker script; and "-x" permitted specifying arbitrary compiler input languages beyond those supported by cgo. "--sysroot" and "-target" are now disallowed in "#cgo" flags, "-isysroot" and "-Wl,-syslibroot" are verified not to point to regular files, and "-x" is restricted to the C, C++, Objective-C, and assembler languages supported by cgo.

This issue affects iSTAR Ultra: before 6.9.2.CU02; iSTAR Ultra SE: before 6.9.2.CU02; iSTAR Ultra G2: before 6.9.2.CU02; iSTAR Ultra G2 SE: before 6.9.2.CU02; iSTAR Edge G2: before 6.9.2.CU02.

Pillow: Heap buffer overflow saving TIFF with libtiff when tags override image size

Pillow is a Python imaging library. From 2.3.0 through 12.3.0, Pillow applications that save compressed TIFF images through libtiff can pass attacker-controlled image geometry tags to the encoder while allocating its row buffer from the actual image dimensions. The affected TiffImagePlugin._save path allows ImageWidth, ImageLength, or SamplesPerPixel from exif=, tiffinfo=, or a source TIFF IFD to make libtiff consume a larger scanline than the buffer supplied by ImagingLibTiffEncode. This can read heap memory into the generated TIFF or crash the process. When TIFF Predictor 2 is enabled, libtiff can rewrite the oversized scanline in place and corrupt memory beyond the buffer. A carried-over PlanarConfiguration value of 2 instead makes libtiff use a shorter scanline and can produce an undecodable output file, but is not established to cause the out-of-bounds access. This issue is fixed in version 13.0.0.

Deserialization allow-list bypass via anonymous-type misdetection in BSON object deserialization

A deserialization type-restriction control in the BSON serialization component can be bypassed because the check used to recognize a class of compiler-generated types relies on an overly permissive heuristic rather than a precise identification. An unauthorized party able to supply BSON content that an application later deserializes into a loosely typed member can cause types outside the intended allow-list to be constructed and populated with unauthorized party-supplied values inside the consuming application. This can lead to unexpected object state and errors in downstream application logic. No elevated privileges beyond the ability to place unauthorized party-influenced content in the deserialization path are required.

Remote code execution via generic-type allow-list bypass in BSON object deserialization

A type allow-list bypass in the BSON serialization library of the MongoDB C# Driver allows a type-restriction check to be circumvented when polymorphic data is deserialized into loosely typed members. An unauthorized party who can supply or plant BSON/JSON data that the application later deserializes can cause the application process to instantiate .NET types outside the intended allow-list and populate them with unauthorized party-controlled values. In applications that contain a suitable gadget type, this can lead to arbitrary code execution in the context of the application, with corresponding loss of confidentiality, integrity, and availability. No special privileges beyond the ability to introduce data the application reads are required.

GPU DDK - Write UAF in OSDebugSignalPID due to incorrect management of PID resources

Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot. The weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.

GPU DDK - OOB write for mappings larger than 4GB due to integer overflow in PVRDmaBufOpsMapCommon

Software installed and run as a non-privileged user may conduct GPU system calls to trigger an integer overflow and allow OOB writes to GPU buffers. The integer overflow caused when mapping a GPU buffer >4GB causes corruption of array length, and can lead to kernel panics or out of bounds access.

ExcelJS through 4.4.0 Memory Exhaustion via Oversized Image Anchor Column

ExcelJS through 4.4.0 contains a memory exhaustion vulnerability that allows attackers to crash applications by supplying a workbook with an unbounded image anchor column in the drawing part. Attackers can set an anchor column such as 300000000 in xl/drawings/drawing1.xml so reading getImages() anchor positions makes Worksheet.getColumn allocate millions of Column objects and abort with a heap out-of-memory error.

OpenEMR before 8.5.0 Global Configuration Override via user_settings.php

OpenEMR before 8.5.0 contains an authorization bypass vulnerability that allows authenticated users to override system-wide global configuration values by storing global-prefixed keys through library/ajax/user_settings.php. Attackers can submit lab or target parameters with global: prefixed setting names to disable audit logging, weaken password policies, or alter security-sensitive settings persistently for their sessions.

Dbus: infinite cpu-spin loop in libdbus socket transport when epipe is received during write operations

A flaw was found in dbus. A local attacker can exploit this vulnerability by connecting to an affected service, requesting a response, and stopping socket reads while keeping the connection open. Because the socket transport handles broken pipe write errors as retryable, the application enters a continuous retry loop. This can lead to excessive CPU consumption, resulting in a denial of service (DoS) for the target process.

Unexpected code execution via escaped quotes in //go:cgo_ldflag in cmd/go and cmd/compile

Building a malicious package that uses cgo could bypass "#cgo LDFLAGS" validation and cause unexpected code execution at build time, or cause the go command to panic, via crafted quoting in "//go:cgo_ldflag" directives. When "cmd/cgo" generates "_cgo_gotypes.go", it quotes each "#cgo LDFLAGS" argument with strconv.Quote in a "//go:cgo_ldflag" directive, but "cmd/compile" and "cmd/go" parsed those directives by splitting on raw quote characters without handling backslash escapes or unquoting the string. This mismatch allowed disallowed linker flags or unvalidated linker search paths to be smuggled past the go command's flag checks and passed to the external linker. In addition, deduplicating LDFLAGS in the go command could panic with an out-of-bounds slice index when a prefix of the flag list matched near the end of the slice. "cmd/compile" and "cmd/go" now properly handle backslash-escaped quotes and unquote "//go:cgo_*" pragma strings with strconv.Unquote, and the slice bounds check in processCgoOutputs has been fixed.

Software installed and run as a non-privileged user may conduct improper GPU system calls to the execution of an error path that triggers an OOB read & write. An error can be triggered which causes the index of the array element to be cleaned up by the error path would be outside of the array bounds.

WP Ultimate CSV Importer < 9.2 - Multisite Subsite Admin+ Network-Wide PHP Code Execution via Media Import

The WP Ultimate CSV Importer WordPress plugin before 9.2 does not restrict the destination filename and extension, nor validate the fetched content type, when importing remote media, allowing an Administrator of a Multisite subsite to write and execute arbitrary PHP in the shared WordPress context despite not being a Network Administrator and being unable to install WP Ultimate CSV Importer WordPress plugin before 9.2 or edit files.

Linker flag injection via cgo_import_dynamic and PE DLL names in cmd/cgo, cmd/compile, and cmd/link

Building a malicious package that uses "//go:cgo_import_dynamic" or links against a crafted PE object on Windows could pass unsafe library arguments to the external linker. The compiler only checked the first character of the library name in "//go:cgo_import_dynamic" directives and skipped validation in cgo-generated files. In addition, on Windows, "cmd/cgo" and "cmd/link" did not validate imported DLL names extracted from PE object files before emitting "-l<name>" flags for the external linker, allowing a crafted DLL name containing ".." path traversal or special characters to reference arbitrary files on disk. The compiler now validates every character of the library name in "//go:cgo_import_dynamic" directives (including in cgo-generated files on Windows) and rejects ".." path traversal, and "cmd/cgo" and "cmd/link" reject PE imported DLL names containing path separators, "..", ":", or leading "-" or "@".
