Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Deserialization of Untrusted Data: The use of standard Java object deserialization (readObject) on untrusted bitmap data can allow attackers to execute arbitrary code or trigger denial of service before class validation occurs. Replacing this with explicit primitive-by-primitive reading from a DataInput is necessary to enforce strict type and structure boundaries during restoration.
