CVE-2003-0143
HighSummary
The pop_msg function in qpopper 4.0.x before 4.0.5fc2 does not null terminate a message buffer after a call to Qvsnprintf, which could allow authenticated users to execute arbitrary code via a buffer overflow in a mdef command with a long macro name.
Risk Assessment
The organization may be exposed to arbitrary code execution by authenticated users, potentially leading to serious security breaches.
Recommendation
It is recommended to update qpopper to version 4.0.5fc2 or later to mitigate this vulnerability.
