Juniper: >> Ptx12008 Security Vulnerabilities
A Function Call With Incorrect Argument Type vulnerability in the sensor interface of Juniper Networks Junos OS Evolved on PTX Series allows a network-based, authenticated attacker with low privileges to cause a complete Denial of Service (DoS).
If colored SRTE policy tunnels are provisioned via PCEP, and gRPC is used to monitor traffic in these tunnels, evo-aftmand crashes and doesn't restart which leads to a complete and persistent service impact. The system has to be manually restarted to recover. The issue is seen only when the Originator ASN field in PCEP contains a value larger than 65,535 (32-bit ASN). The issue is not reproducible when SRTE policy tunnels are statically configured.
This issue affects Junos OS Evolved on PTX Series:
* all versions before 22.4R3-S9-EVO,
* 23.2 versions before 23.2R2-S6-EVO,
* 23.4 versions before 23.4R2-S7-EVO,
* 24.2 versions before 24.2R2-S4-EVO,
* 24.4 versions before 24.4R2-S2-EVO,
* 25.2 versions before 25.2R1-S2-EVO, 25.2R2-EVO.

A Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in the advanced forwarding toolkit (evo-aftmand/evo-pfemand) of Juniper Networks Junos OS Evolved on PTX Series or QFX5000 Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).An attacker sending crafted multicast packets will cause line cards running evo-aftmand/evo-pfemand to crash and restart or non-line card devices to crash and restart. Continued receipt and processing of these packets will sustain the Denial of Service (DoS) condition.
This issue affects Junos OS Evolved PTX Series:
* All versions before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-EVO,
* from 24.2 before 24.2R2-EVO,
* from 24.4 before 24.4R2-EVO.
This issue affects Junos OS Evolved on QFX5000 Series:
* 22.2-EVO version before 22.2R3-S7-EVO,
* 22.4-EVO version before 22.4R3-S7-EVO,
* 23.2-EVO versions before 23.2R2-S4-EVO,
* 23.4-EVO versions before 23.4R2-S5-EVO,
* 24.2-EVO versions before 24.2R2-S1-EVO,
* 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO.
This issue does not affect Junos OS Evolved on QFX5000 Series versions before: 21.2R2-S1-EVO, 21.2R3-EVO, 21.3R2-EVO, 21.4R1-EVO, and 22.1R1-EVO.
