A segmentation fault (SEGV) flaw was found in the Fribidi package and affects the fribidi_remove_bidi_marks() function of the lib/fribidi.c file. This flaw allows an attacker to pass a specially crafted file to Fribidi, leading to a crash and causing a denial of service.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
