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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product dereferences a pointer that it expects to be valid but is NULL.
