CVE-2020-17360: n/a vulnerability

CVE-2020-17360: An issue was discovered in ReadyTalk Avian 1.2.0.

An issue was discovered in ReadyTalk Avian 1.2.0. The vm::arrayCopy method defined in classpath-common.h contains multiple boundary checks that are performed to prevent out-of-bounds memory read/write. However, two of these boundary checks contain an integer overflow that leads to a bypass of these checks, and out-of-bounds read/write. NOTE: This vulnerability only affects products that are no longer supported by the maintainer

Security readout for executives and security teams

ReadyTalk Avian 1.2.0 has an integer overflow in a JVM array-copy routine that can bypass bounds checks and cause out-of-bounds memory reads or writes. The source states the affected product is no longer supported, so organizations should treat any remaining use as legacy risk requiring replacement or isolation. Exposure appears limited to environments still embedding or running ReadyTalk Avian 1.2.0. Modern exposure is likely uncommon, but legacy appliances, bundled runtimes, or archived internal tools may still carry it. Prioritize as a legacy software removal issue, not as a confirmed emergency. If Avian 1.2.0 is present in exposed or business-critical systems, escalate remediation because the maintainer no longer supports the product. Mitigation focus: Inventory systems for ReadyTalk Avian 1.2.0 or bundled Avian runtimes.; Check ReadyTalk or project guidance for any archived migration notes.; Replace unsupported Avian usage with a maintained runtime where feasible..
