CVE-2010-1646

Status Candidate

Overview

The secure path feature in env.c in sudo 1.3.1 through 1.6.9p22 and 1.7.0 through 1.7.2p6 does not properly handle an environment that contains multiple PATH variables, which might allow local users to gain privileges via a crafted value of the last PATH variable.

Ubuntu Security Notice 956-1
Posted Jul 1, 2010
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 956-1 - Evan Broder and Anders Kaseorg discovered that sudo did not properly sanitize its environment when configured to use secure_path (the default in Ubuntu). A local attacker could exploit this to execute arbitrary code as root if sudo was configured to allow the attacker to use a program that interpreted the PATH environment variable.

Debian Linux Security Advisory 2062-1
Posted Jun 18, 2010
Authored by Debian | Site debian.org

Debian Linux Security Advisory 2062-1 - Anders Kaseorg and Evan Broder discovered a vulnerability in sudo, a program designed to allow a sysadmin to give limited root privileges to users, that allows a user with sudo permissions on certain programs to use those programs with an untrusted value of PATH. This could possibly lead to certain intended restrictions being bypassed, such as the secure_path setting.
