Description

A local overflow exists in Orville Write. The "amin" binary fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request to the environment variable, a malicious user can cause arbitrary code execution with elevated privileges, possibly root, if the program was installed setuid, or "tty" group privileges, if the program was installed setgid, resulting in a loss of integrity.

Classification

Location: Local Access Required
Attack Type: Input Manipulation
Impact: Loss of Integrity
Exploit: Exploit Public

Solution

Upgrade to version 2.54 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
