Multiple stack-based buffer overflow vulnerabilities exist in the readOFF functionality of libigl v2.5.0. A specially crafted .off file can lead to stack-based buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.This vulnerability concerns the header parsing occuring while processing an .off file via the readOFF function.

We can see above that at [0] a stack-based buffer called comment is defined with an hardcoded size of 1000 bytes. The call to fscanf at [1] is unsafe and if the first line of the header of the .off files is longer than 1000 bytes it will overflow the header buffer.
