The Hummingbird Client Connector, bundled with EMC Documentum eRoom’s Indexing Server, has a buffer overflow vulnerability. Making an unspecified request can result in a stack-based buffer overflow. A remote, unauthenticated attacker could exploit this to execute arbitrary code.
Documentum eRoom versions 7.x are affected.
