CVE-2026-32741 libheif has a heap buffer overflow in decode_mask_image()

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and below contain a heap buffer overflow in MaskImageCodec::decodemaskimage. When decoding a HEIF file containing a mask image mski, the function copies the full iloc extent data into a pixel buffer using memcpydst,...

CVE-2026-32741

CVE-2026-32741 affects libheif 1.21.2 and earlier. The heap buffer overflow occurs in MaskImageCodec::decode_mask_image() when decoding a HEIF file containing a mask image; the function copies data.size() bytes into a pixel buffer sized by image dimensions using a single memcpy without an upper-b...

BIT-MONGODB-2026-8202 Post-authentication CPU utilization DoS via $trim/$ltrim/$rtrim operators

Using a densely populated chars mask and a large input string in the MongoDB aggregation operators $trim, $ltrim, and $rtrim, an authenticated user with aggregation permissions can pin CPU utilization at 100% for an extended period of time. This issue impacts MongoDB Server v7.0 versions prior to...

libheif 安全漏洞

LibHEIF is a open-source decoder and encoder for the ISO/IEC 23008-12:2017 HEIF file format developed by Struktur. Versions of LibHEIF prior to 1.21.2 contain security vulnerabilities. These vulnerabilities stem from a heap buffer overflow in the MaskImageCodec::decodemaskimage function, where no...

Backdooring Masked Diffusion Language Models

Masked diffusion language models MDLMs are emerging as a compelling new paradigm for text generation, but their training-time security remains largely unexplored. Existing backdoor attacks on Gaussian diffusion models or autoregressive language models do not directly apply to MDLMs because MDLMs...
