Type:
CWE-121
Stack-based Buffer Overflow
Publication date:

Last modified:

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 &#39;set security certificates&#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&#39;s command interpreter, or potentially trigger a stack-based buffer overflow.<br />
