Summary
Junos OS is prone to a denial of service vulnerability in RPD.
Insight
Insight
On Junos OS devices where the BGP add-path feature is enabled with 'send' option or with both 'send' and 'receive' options, a network based attacker can cause the Junos OS rpd daemon to crash and restart. Repeated crashes of the rpd daemon can result in an extended denial of service condition. Junos OS devices that do not have the BGP add-path feature enabled are not affected by this issue. Junos OS devices that only have the 'receive' option with BGP add-path feature enabled are not affected by this issue.
Affected Software
Affected Software
Junos OS 12.1, 12.3, 13.3, 14.1, 14.2 and 15.1.
Detection Method
Detection Method
Checks if a vulnerable OS build is present on the target host.
Solution
Solution
New builds of Junos OS software are available from Juniper. As a workaround disable the BGP add-path feature completely or disable the 'send' option of BGP add-path.
