========================================================================== Ubuntu Security Notice USN-1140-2 May 31, 2011
pam regression ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS
Summary:
The USN-1140-1 PAM update caused cron to stop working.
Software Description: - pam: Pluggable Authentication Modules
Details:
USN-1140-1 fixed vulnerabilities in PAM. A regression was found that caused cron to stop working with a "Module is unknown" error. As a result, systems configured with automatic updates will not receive updates until cron is restarted, these updates are installed or the system is rebooted. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Marcus Granado discovered that PAM incorrectly handled configuration files with non-ASCII usernames. A remote attacker could use this flaw to cause a denial of service, or possibly obtain login access with a different users username. This issue only affected Ubuntu 8.04 LTS. (CVE-2009-0887) It was discovered that the PAM pam_xauth, pam_env and pam_mail modules incorrectly handled dropping privileges when performing operations. A local attacker could use this flaw to read certain arbitrary files, and access other sensitive information. (CVE-2010-3316, CVE-2010-3430, CVE-2010-3431, CVE-2010-3435) It was discovered that the PAM pam_namespace module incorrectly cleaned the environment during execution of the namespace.init script. A local attacker could use this flaw to possibly gain privileges. (CVE-2010-3853) It was discovered that the PAM pam_xauth module incorrectly handled certain failures. A local attacker could use this flaw to delete certain unintended files. (CVE-2010-4706) It was discovered that the PAM pam_xauth module incorrectly verified certain file properties. A local attacker could use this flaw to cause a denial of service. (CVE-2010-4707)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.04: libpam-modules 1.1.2-2ubuntu8.3 libpam0g 1.1.2-2ubuntu8.3
Ubuntu 10.10: libpam-modules 1.1.1-4ubuntu2.3 libpam0g 1.1.1-4ubuntu2.3
Ubuntu 10.04 LTS: libpam-modules 1.1.1-2ubuntu5.3 libpam0g 1.1.1-2ubuntu5.3
Ubuntu 8.04 LTS: libpam-modules 0.99.7.1-5ubuntu6.4 libpam0g 0.99.7.1-5ubuntu6.4
In general, a standard system update will make all the necessary changes.
