Description
libdisplay-info through 0.4.0 contains a heap out-of-bounds read vulnerability in the DisplayID v1 section parser in displayid.c that occurs when a data block's declared length exceeds the section. Attackers can supply a crafted EDID from a malicious monitor, KVM, capture device, or EDID file to make is_all_zeroes read past the buffer, causing a possible crash.
