When Modalities Fail to Tango: Conformal Backdoor Detection in Multimodal Contrastive Learning

Backdoor attacks in multimodal contrastive learning MCL have garnered growing attention in recent years, as many downstream tasks critically depend on pre-trained MCL models. Existing detection-based defenses predominantly rely on the CLIPScore metric, under the assumption that poisoned pairs...

JLSEC-2026-789 A malicious h.265 bitstream can cause an out-of-bounds write in libde265

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in decodercontext::processreferencepictureset libde265/decctx.cc:1376. The root cause is a missing aggregate bound check on predicted...
