CVE-2010-3853

Publication date 24 January 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

pam_namespace.c in the pam_namespace module in Linux-PAM (aka pam) before 1.1.3 uses the environment of the invoking application or service during execution of the namespace.init script, which might allow local users to gain privileges by running a setuid program that relies on the pam_namespace PAM check, as demonstrated by the sudo program.
