CVE-2022-22228: Junos OS: IPv6 OAM SRv6 network-enabled devices are vulnerable to Denial of Service (DoS) due to RPD memory leak upon receipt of specific a IPv6 packet
First published: Tue Oct 18 2022(Updated: )
An Improper Validation of Specified Type of Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS allows an attacker to cause an RPD memory leak leading to a Denial of Service (DoS). This memory leak only occurs when the attacker's packets are destined to any configured IPv6 address on the device. This issue affects: Juniper Networks Junos OS 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 21.1R1.
