A BGP UPDATE containing a specifically crafted set of transitive attributes can cause corruption of memory ultimately leading to an RPD routing process crash and restart. The crash was only achieved through in-house routing protocol fuzz testing. This issue only affects routers supporting 4-byte AS numbers, introduced starting with Junos OS 9.1. Additionally, the router is only vulnerable if the BGP peer does not support 4-byte AS numbers. This issue was found during internal product security testing.
