CVE-2020-27828

Estado: ModificadaAlta (7.8)—

There's a flaw in jasper's jpc encoder in versions prior to 2.0.23. Crafted input provided to jasper by an attacker could cause an arbitrary out-of-bounds write. This could potentially affect data confidentiality, integrity, or application availability.
