Package : sudo Version : 1.7.4p4-2.squeeze.5 CVE ID : CVE-2014-0106 CVE-2014-9680 Debian Bug : #772707 This update fixes the CVEs described below. CVE-2014-0106 Todd C. Miller reported that if the env_reset option is disabled in the sudoers file, the env_delete option is not correctly applied to environment variables specified on the command line. A malicious user with sudo permissions may be able to run arbitrary commands with elevated privileges by manipulating the environment of a command the user is legitimately allowed to run. CVE-2014-9680 Jakub Wilk reported that sudo preserves the TZ variable from a user's environment without any sanitization. A user with sudo access may take advantage of this to exploit bugs in the C library functions which parse the TZ environment variable or to open files that the user would not otherwise be able to open. The latter could potentially cause changes in system behavior when reading certain device special files or cause the program run via sudo to block. For the oldstable distribution (squeeze), these problems have been fixed in version 1.7.4p4-2.squeeze.5. For the stable distribution (wheezy), they have been fixed in version 1.8.5p2-1+nmu2. We recommend that you upgrade your sudo packages. -- Ben Hutchings - Debian developer, kernel team member
