An Improper Preservation of Consistency Between Independent Representations of Shared State vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). If the device is very busy for example while executing a series of show commands on the CLI one or more SFPs might not be detected anymore. The system then changes its state to "unplugged" which is leading to traffic impact and at least a partial DoS. Once the system is less busy the port states return to their actual value. Indicators of compromise are log messages about unplugged SFPs and corresponding syspld messages without any physical or environmental cause. These can be checked by issuing the following commands: user@device# show log messages | match unplugged %PFE-6: fpc0 sfp-0/1/2 SFP unplugged %PFE-6: fpc0 sfp-0/1/3 SFP unplugged The following log messages will also be seen when this issue happens: fpc0 Error tvp_drv_syspld_read: syspld read failed for address <address> fpc0 Error[-1]:tvp_optics_presence_get - Syspld read failed for port <pic/port> fpc0 optics pres failed(-1) for pic <pic> port <port> fpc0 tvp_drv_syspld_read: i2c access retry count 200 This issue affects Juniper Networks Junos OS on EX2300 Series, EX3400 Series: All versions prior to 18.4R3-S11; 19.1 versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R2-S7, 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R2.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based, attacker to cause Denial of Service (DoS). A PFE crash will happen when a GPRS Tunnel Protocol (GTP) packet is received with a malformed field in the IP header of GTP encapsulated General Packet Radio Services (GPRS) traffic. The packet needs to match existing state which is outside the attackers control, so the issue cannot be directly exploited. The issue will only be observed when endpoint address validation is enabled. This issue affects Juniper Networks Junos OS on SRX Series: 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3-S3; 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 21.4R1-S2, 21.4R2; 22.1 versions prior to 22.1R1-S1, 22.1R2.

An Improper Release of Memory Before Removing Last Reference vulnerability in the Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Juniper Networks Junos OS allows unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On all MX and SRX platforms, if the SIP ALG is enabled, receipt of a specific SIP packet will create a stale SIP entry. Sustained receipt of such packets will cause the SIP call table to eventually fill up and cause a DoS for all SIP traffic. The SIP call usage can be monitored by "show security alg sip calls". To be affected the SIP ALG needs to be enabled, either implicitly / by default or by way of configuration. Please verify on SRX with: user@host> show security alg status | match sip SIP : Enabled Please verify on MX whether the following is configured: [ services ... rule <rule-name> (term <term-name>) from/match application/application-set <name> ] where either a. name = junos-sip or an application or application-set refers to SIP: b. [ applications application <name> application-protocol sip ] or c.
