Last modified
CVE-2024-39564 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. This is a similar, but different vulnerability than the issue reported as CVE-2024-39549. A double-free vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This double free of memory is causing an rpd crash, leading to a Denial of Service (DoS). This issue affects: Junos OS: * from 22.4 before 22.4R3-S4. Junos OS Evolved: * from 22.4 before 22.4R3-S4-EVO.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
