JDBC driver Heap Buffer Overflow DoS

The vulnerability of the userOverridesAsString method in the JDBC driver handling library in c3p0 is related to incorrect code generation management. Exploiting this vulnerability allows an attacker to execute arbitrary code using specially created Java serializable objects and instances of...

SUSE CVE-2026-27830

c3p0, a JDBC Connection pooling library, is vulnerable to attack via maliciously crafted Java-serialized objects and javax.naming.Reference instances. Several c3p0 ConnectionPoolDataSource implementations have a property called userOverridesAsString which conceptually represents a Map. Prior to...

CVE-2026-27830

A flaw was found in c3p0, a Java Database Connectivity JDBC Connection pooling library. This vulnerability allows an attacker to achieve arbitrary code execution by providing maliciously crafted Java-serialized objects or javax.naming.Reference instances. By manipulating the userOverridesAsString...

CVE-2026-27830

CVE-2026-27830 affects the c3p0 JDBC connection pool. Before 0.12.0, the property userOverridesAsString was stored as a hex-encoded serialized object, enabling an attacker to reset it and trigger deserialization that could load code from a remote factoryClassLocation via embedded JNDI references....
