Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GoBGP (github.com/osrg/gobgp/v3) versions before 3.35.0 are affected, and the source gives few details beyond the packet parser in the RTR package not checking that the input length matches the bytes actually available for an RTR message. The source does not describe what an attacker must do to trigger it or what the impact would be. Upgrade github.com/osrg/gobgp/v3 to 3.35.0 or later. No fixed version is listed for github.com/osrg/gobgp.
