A segmentation fault (SEGV) flaw was found in the Fribidi package and affects the fribidiremovebidimarks() 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 heap based buffer overflow was found in fribidicaprtltounicode.
