Original advisory details:

 It was discovered that FriBidi incorrectly handled processing of input strings
 resulting in memory corruption. An attacker could use this issue to cause
 FriBidi to crash, resulting in a denial of service, or potentially execute
 arbitrary code. (CVE-2022-25308)

 It was discovered that FriBidi incorrectly validated input data to its CapRTL
 unicode encoder, resulting in memory corruption. An attacker could use this
 issue to cause FriBidi to crash, resulting in a denial of service, or
 potentially execute arbitrary code. (CVE-2022-25309)

 It was discovered that FriBidi incorrectly handled empty input when removing
 marks from unicode strings, resulting in a crash. An attacker could use this
 to cause FriBidi to crash, resulting in a denial of service, or potentially
 execute arbitrary code. (CVE-2022-25310)");
