Description
A flaw was found in htslib, a library for reading and writing bioinformatics file formats. A local user could exploit a heap buffer overflow vulnerability by opening a specially crafted CRAM file. This flaw occurs due to incorrect handling of certain CRAM format records, leading to reading and writing a single byte beyond a heap allocation. Successful exploitation could result in a program crash, data corruption, or potentially arbitrary code execution.
