CVE-2007-1995
bgpd/bgp_attr.c in Quagga 0.98.6 and earlier, and 0.99.6 and earlier 0.99 versions, does not validate length values in the MP_REACH_NLRI and MP_UNREACH_NLRI attributes, which allows remote attackers to cause a denial of service (daemon crash or exit)…
Does this matter?
Lower severity and a low EPSS score (1.74%). Track it; it rarely justifies an emergency change on its own.
Description
bgpd/bgp_attr.c in Quagga 0.98.6 and earlier, and 0.99.6 and earlier 0.99 versions, does not validate length values in the MP_REACH_NLRI and MP_UNREACH_NLRI attributes, which allows remote attackers to cause a denial of service (daemon crash or exit) via crafted UPDATE messages that trigger an assertion error or out of bounds read.
