Doc Text:
A flaw was found in snappy-java. An attacker can trigger a buffer overflow vulnerability in the `Snappy.compress(ByteBuffer, ByteBuffer)` function by providing specially crafted, incompressible data. This vulnerability allows the attacker to write past the end of the destination buffer, corrupting off-heap memory. The corruption ultimately leads to the termination of the Java Virtual Machine (JVM), resulting in a denial of service.

Description OSIDB Bzimport 2026-09-22 18:39:48 UTC 
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.
