A heap-based buffer overflow flaw was found in the Fribidi package and
affects the fribidi_cap_rtl_to_unicode() function of the
fribidi-char-sets-cap-rtl.c file. This flaw allows an attacker to pass a
specially crafted file to the Fribidi application with the ‘–caprtl’
option, leading to a crash and causing a denial of service.
