David Gstir discovered that libcap2 incorrectly handled certain return
codes. An attacker could possibly use this issue to cause libcap2 to
consume memory, leading to a denial of service. (CVE-2023-2602)
Richard Weinberger discovered that libcap2 incorrectly handled certain long
input strings. An attacker could use this issue to cause libcap2 to crash,
resulting in a denial of service, or possibly execute arbitrary code.
