| Doc Text: |
A flaw was found in GoBGP. A remote attacker could send a specially crafted Border Gateway Protocol (BGP) UPDATE message that exploits improper handling of 4-byte Autonomous System (AS) attributes, causing an internal slice index shift. This leads to a runtime error, resulting in a Denial of Service (DoS) condition.
