Title
Junos OS: MX Series with SPC3 line card: Port flaps causes rtlogd memory leak leading to Denial of Service
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the rtlogd process of Juniper Networks Junos OS on MX Series with SPC3 allows an unauthenticated, adjacent attacker to trigger internal events cause ( which can be done by repeated port flaps) to cause a slow memory leak, ultimately leading to a Denial of Service (DoS).
Memory can only be recovered by manually restarting rtlogd process.
The memory usage can be monitored using the below command.
user@host> show system processes extensive | match rtlog

Title
Junos OS and Junos OS Evolved: Receipt of malformed BGP path attributes leads to a memory leak
Summary
A Missing Release of Memory after Effective Lifetime 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 memory is not properly freed in all circumstances, leading to a Denial of Service (DoS).
Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd).
Memory utilization could be monitored by:
user@host> show system memory or show system monitor memory status
This issue affects:
Junos OS: * All versions before 21.2R3-S8,
* from 21.4 before 21.4R3-S8,
* from 22.2 before 22.2R3-S4,
* from 22.3 before 22.3R3-S3,
* from 22.4 before 22.4R3-S3,
* from 23.2 before 23.2R2-S1,
* from 23.4 before 23.4R1-S2, 23.4R2.
Junos OS Evolved:
* All versions before 21.2R3-S8-EVO,
* from 21.4 before 21.4R3-S8-EVO,
* from 22.2 before 22.2R3-S4-EVO,
* from 22.3 before 22.3R3-S3-EVO,
* from 22.4 before 22.4R3-S3-EVO,
* from 23.2 before 23.2R2-S1-EVO,
* from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO.

Title
Junos OS and Junos OS Evolved: Flaps of BFD sessions with authentication cause a ppmd memory leak
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the Periodic Packet Management Daemon (ppmd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause a
Denial-of-Service (DoS).
When a BFD session configured with authentication flaps, ppmd memory can leak. Whether the leak happens depends on a race condition which is outside the attackers control. This issue only affects BFD operating in distributed aka delegated (which is the default behavior) or inline mode.
Whether the leak occurs can be monitored with the following CLI command:
> show ppm request-queue
FPC Pending-request
fpc0 2
request-total-pending: 2
where a continuously increasing number of pending requests is indicative of the leak.
This issue affects:
Junos OS:
* All versions before 21.2R3-S8,
* 21.4 versions before 21.4R3-S7,
* 22.1 versions before 22.1R3-S4,
* 22.2 versions before 22.2R3-S4,
* 22.3 versions before 22.3R3,
* 22.4 versions before 22.4R2-S2, 22.4R3.
Junos OS Evolved:
* All versions before 21.2R3-S8-EVO,
* 21.4-EVO versions before 21.4R3-S7-EVO,
* 22.2-EVO versions before 22.2R3-S4-EVO,
* 22.3-EVO versions before 22.3R3-EVO,
* 22.4-EVO versions before 22.4R3-EVO.

Title
Junos OS and Junos OS Evolved: A link flap causes patroot memory leak which leads to rpd crash
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause an rpd crash, leading to Denial of Service (DoS).
On all Junos OS and Junos OS Evolved platforms, when traffic engineering is enabled for OSPF or ISIS, and a link flaps, a patroot memory leak is observed. This memory leak, over time, will lead to an rpd crash and restart.
The memory usage can be monitored using the below command.
user@host> show task memory detail | match patroot

Title
Junos OS and Junos OS Evolved: In a jflow scenario continuous route churn will cause a memory leak and eventually an rpd crash
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
In a Juniper Flow Monitoring (jflow) scenario route churn that causes BGP next hops to be updated will cause a slow memory leak and eventually a crash and restart of rpd.
Thread level memory utilization for the areas where the leak occurs can be checked using the below command:
user@host> show task memory detail | match so_in
so_in6 28 32 344450 11022400 344760 11032320

Title
Junos OS: MX Series with SPC3, and SRX Series: If specific IPsec parameters are negotiated iked will crash due to a memory leak
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the IKE daemon (iked) of Juniper Networks Junos OS on MX Series with SPC3, and SRX Series allows an administratively adjacent attacker which is able to successfully establish IPsec tunnels to cause a Denial of Service (DoS).
If specific values for the IPsec parameters local-ip, remote-ip, remote ike-id, and traffic selectors are sent from the peer, a memory leak occurs during every IPsec SA rekey which is carried out with a specific message sequence. This will eventually result in an iked process crash and restart.
The iked process memory consumption can be checked using the below command:
user@host> show system processes extensive | grep iked
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND
56903 root 31 0 4016M 2543M CPU0 0 2:10 10.50% iked
This issue affects Juniper Networks Junos OS:
* All versions earlier than 20.4R3-S9;
* 21.2 versions earlier than 21.2R3-S7;
* 21.3 versions earlier than 21.3R3-S5;
* 21.4 versions earlier than 21.4R3-S4;

Title
Junos OS: MX Series: MPC3E memory leak with PTP configuration
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).
If an MX Series device receives PTP packets on an MPC3E that doesn't support PTP this causes a memory leak which will result in unpredictable behavior and ultimately in an MPC crash and restart.
To monitor for this issue, please use the following FPC vty level commands:
show heap
shows an increase in "LAN buffer" utilization and
show clksync ptp nbr-upd-info
shows non-zero "Pending PFEs" counter.
This issue affects Juniper Networks Junos OS on MX Series with MPC3E:
* All versions earlier than 20.4R3-S3;
* 21.1 versions earlier than 21.1R3-S4;
* 21.2 versions earlier than 21.2R3;
* 21.3 versions earlier than 21.3R2-S1, 21.3R3;
* 21.4 versions earlier than 21.4R2;
* 22.1 versions earlier than 22.1R2.

Title
Cisco IOS XR Software Packet Memory Exhaustion Vulnerability
Summary
A vulnerability in the multicast traceroute version 2 (Mtrace2) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to exhaust the UDP packet memory of an affected device.
This vulnerability exists because the Mtrace2 code does not properly handle packet memory. An attacker could exploit this vulnerability by sending crafted packets to an affected device. A successful exploit could allow the attacker to exhaust the incoming UDP packet memory. The affected device would not be able to process higher-level UDP-based protocols packets, possibly causing a denial of service (DoS) condition.
Note: This vulnerability can be exploited using IPv4 or IPv6.

Mitigation MIT-41
Implementation
Strategy: Libraries or Frameworks
- Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
- For example, glibc in Linux provides protection against free of invalid pointers.
- When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
- To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Architecture and Design
Build and Compilation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
