Vulnerability Details : CVE-2020-17360
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

CWE ids for CVE-2020-17360
-
The product reads data past the end, or before the beginning, of the intended buffer.Assigned by: nvd@nist.gov (Primary)
-
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.Assigned by: nvd@nist.gov (Primary)
-
The product writes data past the end, or before the beginning, of the intended buffer.Assigned by: nvd@nist.gov (Primary)
