{"id":"CVE-2024-39556","state":"PUBLISHED","title":"Junos OS and Junos OS Evolved: Loading a malicious certificate from the CLI may result in a stack-based overflow","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.\n\nBy exploiting the 'set security certificates' 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's command interpreter, or potentially trigger a stack-based buffer overflow.\n\n\nThis issue affects:\n\n Junos OS: \n\n\n  *  All versions before 21.4R3-S7, \n  *  from 22.1 before 22.1R3-S6, \n  *  from 22.2 before 22.2R3-S4, \n  *  from 22.3 before 22.3R3-S3, \n
