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.
