CVE-2025-53367-POC

djvulibremmrexploit 이 프로젝트는 DjVuLibre에서 알려진 힙heap out-of-bounds 쓰기 취약점을 트리거하는 최소한의 C++ 구현을 제공합니다. 이 코드는 버그를 무기화하지 않으며, 문제를 검사하고 이해할 수 있도록 결함이 있는 실행 경로만 재현합니다. 이 취약점은 MMR로 인코딩된 이미지 청크를 위한 파서에서 비롯됩니다. 처리 중에 MMRDecoder::scanruns 함수는 충분한 경계 검사bounds checking를 수행하지 않고 수평 런을 라인 버퍼로 디코딩합니다. 연속된 0-길이 수평 ...

CVE-2026-53293

A flaw was found in the Linux kernel's AMDGPU graphics driver. Multiple issues exist within the AMDGPUINFOREADMMRREG function, including an incorrect order of operations between the reset semaphore and the memory management lock, and memory allocation while holding the reset semaphore. These issu...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write via the scanruns function in the MMRDecoder component. An attacker can cause heap corruption or read sensitive memory by providing specially crafted input that causes the xr pointer to write or read outside the bound...

Matrix Media Repo (MMR) allows untrusted file formats can be thumbnailed, invoking potentially further untrusted decoders

Impact If SVG or JPEGXL thumbnailers are enabled they are disabled by default, a user may upload a file which claims to be either of these types and request a thumbnail to invoke a different decoder in ImageMagick. In some ImageMagick installations, this includes the capability to run Ghostscript...
