DSA-870-1 sudo Detailed Explanation for this Vulnerability Assessment Tavis Ormandy noticed that sudo, a program that provides limited super user rights to specific users, does not clean the environment sufficiently. The SHELLOPTS and PS4 variables are dangerous and are still passed through to the program running as privileged user. This can result in the execution of arbitrary commands as privileged user when a bash script is executed. These vulnerabilities can only be exploited by users who have been granted limited super user rights. For the old stable distribution (woody) this problem has been fixed in version 1.6.6-1.4. For the stable distribution (sarge) this problem has been fixed in version 1.6.8p7-1.2. For the unstable distribution (sid) this problem has been fixed in version 1.6.8p9-3. We recommend that you upgrade your sudo package.
