XORP Link State Advertisement (LSA) denial of service
| xorp-lsa-dos (29658) |  Medium Risk |
Description:
XORP is vulnerable to a denial of service, caused by an out of bounds read when handling Link State Advertisements (LSA). A remote attacker could send a specially-crafted LSA containing an invalid length value to cause the OSPF daemon to crash.
*CVSS:
