Description

The BGP implementation in bgpd in Quagga before 0.99.20.1 does not properly use message buffers for OPEN messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a message associated with a malformed Four-octet AS Number Capability (aka AS4 capability).

• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
