This collective update for sudo provides fixes for the following issues :

  - Security policy bypass when env_reset is disabled.
    (CVE-2014-0106, bnc#866503)

  - Regression in the previous update that causes a     segmentation fault when running 'sudo -s'. (bnc#868444)

  - Command 'who -m' prints no output when using     log_input/log_output sudo options. (bnc#863025)

New sudo packages are available for Slackware 13.0, 13.1, and 13.37 to fix a security issue.

An updated sudo package that fixes one security issue is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root.

A flaw was found in the way sudo handled its blacklist of environment variables. When the 'env_reset' option was disabled, a user permitted to run certain commands via sudo could use this flaw to run such a command with one of the blacklisted environment variables set, allowing them to run an arbitrary command with the target user's privileges. (CVE-2014-0106)

Note: This issue does not affect the default configuration of the sudo package as shipped with Red Hat Enterprise Linux 5.

Red Hat would like to thank Todd C. Miller for reporting this issue.
Upstream acknowledges Sebastien Macke as the original reporter.

All sudo users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Note: This issue does not affect the default configuration of the sudo package as shipped with Scientific Linux 5.

Sebastien Macke discovered that Sudo incorrectly handled blacklisted environment variables when the env_reset option was disabled. A local attacker could use this issue to possibly run unintended commands by using blacklisted environment variables. In a default Ubuntu installation, the env_reset option is enabled by default. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2014-0106)

It was discovered that the Sudo init script set a date in the past on existing timestamp files instead of using epoch to invalidate them completely. A local attacker could possibly modify the system time to attempt to reuse timestamp files. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 12.10 and Ubuntu 13.10. (LP: #1223297).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201406-30 (sudo: Privilege escalation)

    When the Sudo env_reset option is disabled (it is enabled by default),       certain environment variables are not blacklisted as expected.
  Impact :

    A local attacker, authorized to run commands using sudo, can use this       flaw to execute arbitrary code or escalate his privileges.
  Workaround :

    There is no known workaround at this time.

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.
