Description

A Stack-Based Buffer Overflow vulnerability in Juniper Networks Junos OS and Juniper Networks Junos OS Evolved may allow a local, low-privileged attacker with access to the CLI the ability to load a malicious certificate file, leading to a limited Denial of Service (DoS) or privileged code execution.<br /> <br /> By exploiting the &amp;#39;set security certificates&amp;#39; command with a crafted certificate file, a malicious attacker with access to the CLI could cause a crash of the command management daemon (mgd), limited to the local user&amp;#39;s command interpreter, or potentially trigger a stack-based buffer overflow.<br /> <br /> <br /> This issue affects:<br /> <br />  Junos OS: <br /> <br /> <br /> * All versions before 21.4R3-S7, <br /> * from 22.1 before 22.1R3-S6, <br /> * from 22.2 before 22.2R3-S4, <br /> * from 22.3 before 22.3R3-S3, <br /> * from 22.4 before 22.4R3-S2, <br /> * from 23.2 before 23.2R2, <br /> * from 23.4 before 23.4R1-S1, 23.4R2; <br /> <br /> <br /> <br /> <br /> Junos OS Evolved: <br /> <br /> <br /> * All versions before 21.4R3-S7-EVO, <br /> * from 22.1-EVO before 22.1R3-S6-EVO, <br /> * from 22.2-EVO before 22.2R3-S4-EVO, <br /> * from 22.3-EVO before 22.3R3-S3-EVO, <br /> * from 22.4-EVO before 22.4R3-S2-EVO, <br /> * from 23.2-EVO before 23.2R2-EVO, <br /> * from 23.4-EVO before 23.4R1-S1-EVO, 23.4R2-EVO.
