Summary
snappy-java through 1.1.10.8 contains a buffer overflow vulnerability in Snappy.compress(ByteBuffer, ByteBuffer) that writes past the end of the destination buffer. Attackers can supply incompressible data that exceeds the destination buffer's remaining capacity, corrupting off-heap memory and causing JVM termination.
An attacker can trigger a buffer overflow vulnerability in the `Snappy.compress(ByteBuffer, ByteBuffer)` function by providing specially crafted, incompressible data. The corruption ultimately leads to the termination of the Java Virtual Machine (JVM), resulting in a denial of service.
A flaw in snappy-java allows an attacker to terminate an application JVM when attacker-controlled, incompressible data is passed to Snappy.compress(ByteBuffer, ByteBuffer) with an undersized destination buffer. The native compression path can write beyond the supplied buffer and corrupt off-heap memory.
SELinux, non-root execution, and container isolation may limit impact outside the application boundary but do not prevent application-level denial of service. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
Weakness: CWE-787.
Affected products named by the advisory: Red Hat build of Apache Camel 4 for Quarkus 3; Red Hat build of Apache Camel for Spring Boot 4; Red Hat build of Apicurio Registry 3; Red Hat build of Debezium 3; and 8 more.

Mitigation checklist
- Validate destination buffer capacity against maximum theoretical compressed payload size prior to invoking Snappy.compress, or restrict untrusted compressed input vectors at network application boundaries.
