CVE-2023-28980 – Junos OS and Junos OS Evolved: In a BGP rib sharding scenario an rpd crash will happen shortly after a specific CLI command is issued

https://notcve.org/view.php?id=CVE-2023-28980

A Use After Free vulnerability in the routing protocol daemon of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause Denial of Service (DoS). In a rib sharding scenario the rpd process will crash shortly after specific CLI command is issued. This issue is more likely to occur in a scenario with high route scale (>1M routes). This issue affects: Juniper Networks Junos OS * 20.2 version 20.2R3-S5 and later versions prior to 20.2R3-S6; * 20.3 version 20.3R3-S2 and later versions prior to 20.3R3-S5; * 20.4 version 20.4R3-S1 and later versions prior to 20.4R3-S4 * 21.1 version 21.1R3 and later versions prior to 21.1R3-S3; * 21.2 version 21.2R1-S2, 21.2R2-S1 and later versions prior to 21.2R3-S2; * 21.3 version 21.3R2 and later versions prior to 21.3R3; * 21.4 versions prior to 21.4R2-S1, 21.4R3; * 22.1 versions prior to 22.1R2.

CVE-2023-28981 – Junos OS and Junos OS Evolved: If malformed IPv6 router advertisements are received, memory corruption will occur which causes an rpd crash

https://notcve.org/view.php?id=CVE-2023-28981

An Improper Input Validation vulnerability in the kernel of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If the receipt of router advertisements is enabled on an interface and a specifically malformed RA packet is received, memory corruption will happen which leads to an rpd crash. This issue affects: Juniper Networks Junos OS 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R2. Juniper Networks Junos OS Evolved 20.3-EVO version 20.3R1-EVO and later versions; 20.4-EVO versions prior to 20.4R3-S6-EVO; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R2-EVO; 22.1-EVO versions prior to 22.1R2-EVO. • https://supportportal.juniper.net/JSA70607 • CWE-20: Improper Input Validation •

CVE-2023-28984 – Junos OS: QFX Series: The PFE may crash when a lot of MAC addresses are being learned and aged

https://notcve.org/view.php?id=CVE-2023-28984

A Use After Free vulnerability in the Layer 2 Address Learning Manager (l2alm) of Juniper Networks Junos OS on QFX Series allows an adjacent attacker to cause the Packet Forwarding Engine to crash and restart, leading to a Denial of Service (DoS). The PFE may crash when a lot of MAC learning and aging happens, but due to a Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) that is outside the attackers direct control. This issue affects: Juniper Networks Junos OS versions prior to 19.4R3-S10 on QFX Series; 20.2 versions prior to 20.2R3-S7 on QFX Series; 20.3 versions prior to 20.3R3-S6 on QFX Series; 20.4 versions prior to 20.4R3-S5 on QFX Series; 21.1 versions prior to 21.1R3-S4 on QFX Series; 21.2 versions prior to 21.2R3-S3 on QFX Series; 21.3 versions prior to 21.3R3-S3 on QFX Series; 21.4 versions prior to 21.4R3 on QFX Series; 22.1 versions prior to 22.1R3 on QFX Series; 22.2 versions prior to 22.2R2 on QFX Series. • https://supportportal.juniper.net/JSA70610 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

CVE-2023-28975 – Junos OS: The kernel will crash when certain USB devices are inserted

https://notcve.org/view.php?id=CVE-2023-28975

An Unexpected Status Code or Return Value vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated attacker with physical access to the device to cause a Denial of Service (DoS). When certain USB devices are connected to a USB port of the routing-engine (RE), the kernel will crash leading to a reboot of the device. The device will continue to crash as long as the USB device is connected. This issue affects Juniper Networks Junos OS: All versions prior to 19.4R3-S10; 20.2 versions prior to 20.2R3-S7; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3-S2; 22.1 versions prior to 22.1R2-S2, 22.1R3; 22.2 versions prior to 22.2R2, 22.2R3; 22.3 versions prior to 22.3R1-S1, 22.3R2; 22.4 versions prior to 22.4R2. • https://supportportal.juniper.net/JSA70600 • CWE-394: Unexpected Status Code or Return Value CWE-754: Improper Check for Unusual or Exceptional Conditions •

CVE-2023-28964 – Junos OS and Junos OS Evolved: Malformed BGP flowspec update causes RPD crash

https://notcve.org/view.php?id=CVE-2023-28964

An Improper Handling of Length Parameter Inconsistency vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network based, unauthenticated attacker to cause an RPD crash leading to a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Upon receipt of a malformed BGP flowspec update, RPD will crash resulting in a Denial of Service. This issue affects Juniper Networks Junos OS: All versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S6; 18.3 versions prior to 18.3R3-S4; 18.4 versions prior to 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R3-S1; 19.3 versions prior to 19.3R3-S1; 19.4 versions prior to 19.4R3; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2; 20.3 versions prior to 20.3R1-S1, 20.3R2; Juniper Networks Junos OS Evolved: All versions prior to 20.1R3-EVO; 20.2 versions prior to 20.2R2-EVO; 20.3 versions prior to 20.3R2-EVO; • https://supportportal.juniper.net/JSA70588 • CWE-130: Improper Handling of Length Parameter Inconsistency •
