Windows DNS Denial of Service Vulnerability

Integer overflow or wraparound in Windows DNS allows an unauthorized attacker to deny service over a network.

Freedesktop Poppler SampledFunction Function.cc integer overflow

A vulnerability was detected in Freedesktop Poppler 26.07.0. This issue affects the function SampledFunction::SampledFunction of the file poppler/Function.cc of the component SampledFunction. The manipulation of the argument BitsPerSample results in integer overflow. The attack may be performed from remote. The exploit is now public and may be used. The project was informed of the problem early through a bug report but has not responded yet.

Heap write primitive via size round-up wrap during JSON parsing on 32-bit builds

An integer wraparound in an allocation size calculation in the BSON library's JSON parsing code can cause a buffer to be released while a following copy operation still writes through the stale pointer. On builds where sizes are 32 bits, an unauthenticated party able to supply a sufficiently large JSON input to an application that links the library may cause that application to terminate unexpectedly, resulting in denial of service.

libheif hOp_RGB24_32_to_YCbCr Memory Access Error / SEGV

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.19.6, Op_RGB24_32_to_YCbCr::convert_colorspace() stores image-plane strides in an integer width that can overflow for extremely large RGB images created through heif_image_create() and heif_image_add_plane(). The resulting wrapped stride causes the conversion loop in libheif/color-conversion/rgb2yuv.cc to compute an invalid input pointer and read beyond the allocated interleaved plane while heif_context_encode_image() performs RGB-to-YCbCr conversion. This can crash the encoding process. This issue is fixed in version 1.19.6.

Freedesktop Poppler FoFiTrueType.cc mapCodeToGID integer overflow

A vulnerability was determined in Freedesktop Poppler 26.07.0. This affects the function FoFiTrueType::mapCodeToGID of the file fofi/FoFiTrueType.cc. Executing a manipulation of the argument segCnt can lead to integer overflow. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. This patch is called ed2a5538cf0a8d3ff908191eda9b73f91a5f952a. It is advisable to implement a patch to correct this issue.

FluidSynth: DLS ptbl Chunk Integer Overflow

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS parser validates ptbl chunks with the unsigned expression cues * 4 + cbsize without checking whether the multiplication and addition fit in 32 bits. A crafted DLS file can supply a large cues value that wraps the expression and passes the chunk-size check, causing poolcues.resize(cues) to request approximately four gigabytes and the parser to read billions of entries beyond the chunk boundary. The excessive allocation and invalid reads can cause denial of service. Builds with enable-native-dls set to OFF are not exposed. This issue is fixed in version 2.5.6.

ESPAsyncWebServer: Integer overflow in multipart boundary parser causes denial of service

ESPAsyncWebServer is an asynchronous HTTP and WebSocket server library for ESP32, ESP8266, RP2040 and RP2350. Prior to 3.11.1, the multipart/form-data parser in src/WebRequest.cpp stores _boundaryPosition as an 8-bit value while _parseMultipartPostByte processes the boundary. A remote request containing an exactly 256-byte multipart boundary wraps _boundaryPosition from 255 to zero, prevents the boundary parsing loop from terminating, consumes excessive CPU, and triggers a FreeRTOS watchdog reset on affected ESP32 or ESP8266 devices. This issue is fixed in version 3.11.1.

Microsoft Windows PDF Remote Code Execution Vulnerability

Integer overflow or wraparound in Microsoft Windows PDF allows an unauthorized attacker to execute code over a network.

Integer Overflow Privilege Escalation in Android

In multiple locations, there is a possible permission bypass due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Integer Overflow in VPU Causes Local Privilege Escalation

In VPU, there is a possible out-of-bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

msgpack-java through 0.9.12 Integer Overflow via MAP32

msgpack-java through 0.9.12 contains an integer overflow vulnerability in MessageUnpacker.skipValue() when processing MAP32 containers with large element counts. Attackers can supply a MAP32 element count at or above 0x40000000 that wraps when doubled, causing the parser cursor to desynchronize and attacker-controlled data to be returned in place of later fields.

Integer Overflow Permission Bypass Allowing Local Privilege Escalation on Android

In multiple locations, there is a possible permission bypass due to an integer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

Microsoft Windows Search Component Elevation of Privilege Vulnerability

Integer overflow or wraparound in Microsoft Windows Search Component allows an authorized attacker to elevate privileges locally.

In RtcpFbPacket::decodeRtcpFbPacket, there is a possible out of bounds read due to an integer overflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.

An integer overflow was addressed with improved input validation. This issue is fixed in iOS 26.6.1 and iPadOS 26.6.1, macOS Sequoia 15.8, macOS Tahoe 26.6.2, tvOS 27, visionOS 27, watchOS 27. Processing an image may lead to arbitrary code execution.

pcre2: PCRE2: Out-of-bounds write via large pattern input

PCRE2 before 10.48, on 32-bit platforms, has a pcre2_pattern_convert out-of-bounds write when an attacker can provide a large pattern.
