curl: Use-After-Free in SMB connection reuse (req->path dangling pointer after needle destruction)

Summary A heap-use-after-free occurs in smbsendopen at lib/smb.c when curl processes two SMB URLs targeting the same host. The function smbparseurlpath sets req-path as a non-owning pointer into smbc-share connection-owned memory. During connection reuse, the needle connection is freed via...

Arbitrary File Write via Validation/Extraction Path Mismatch in nltk.downloader._unzip_iter()

Description The current Zip Slip hardening in nltk.downloader.validatemember assumes that the path validated with: os.path.abspathos.path.joinroot, member os.path.realpathos.path.joinroot, member is the same path that zipfile.extractmember, root will later write to. That assumption is false for...

Unbounded Frame Count in video/jpeg Base64 Data URL Processing Leads to OOM DoS

Summary The VideoMediaIO.loadbase64 method in vLLM's multimodal processing pipeline splits video/jpeg data URLs by comma delimiters to extract individual JPEG frames, but does not enforce a frame count limit. An attacker can craft a single API request containing thousands of comma-separated...
