Description Vladimir Vasilev 2026-10-16 18:37:51 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

nifti_clib through 3.0.1 contains a stack-based out-of-bounds read and write vulnerability in nifti_convert_n2hdr2nim() because the NIfTI-2 dim[0] value is never range-checked. Attackers can supply a crafted 540-byte NIfTI-2 header read via nifti_image_read() to crash applications or corrupt stack memory.
