CVE-2018-3848: Buffer Overflow
First published: Mon Apr 16 2018(Updated: )
In the ffghbn function in NASA CFITSIO 3.42, specially crafted images parsed via the library can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution.
