Description

According to its self-reported version number, the version of Junos running on the remote device has a denial of service vulnerability. Processing a BGP UPDATE containing a corrupted ATTR_SET attribute can result in an rpd crash.

This issue only affects routers configured for BGP running Junos 10.2 or later that do no thave the 'independent-domain' routing option enabled.

A remote, unauthenticated attacker could exploit this to crash the rpd service.
