상세 설명

A Return of Pointer Value Outside of Expected Range vulnerability in the fileio library of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privilged attacker to cause a Denial-of-Service (DoS).

On EX Series, QFX Series and MX Series a low-privileged attacker issuing a specific 'show l2-learning' or 'show ethernet-switching' command will cause an l2ald crash which will lead to a temporary service impact for all layer 2 services until the process has automatically restarted.

This issue affects EX Series, QFX Series, MX Series:
Junos OS:

all versions before 23.2R2-S7,
23.4 versions before 23.4R2-S7,
24.2 versions before 24.2R2,
24.4 versions before 24.4R1-S2.

Junos OS Evolved:

all versions before 23.2R2-S7-EVO,
23.4 versions before 23.4R2-S8-EVO,
24.2 versions before 24.2R2-EVO,
24.4 versions before 24.4R1-S3-EVO.
