Last modified

CVE-2011-3148 is a vulnerability of currently unknown severity. Stack-based buffer overflow in the _assemble_line function in modules/pam_env/pam_env.c in Linux-PAM (aka pam) before 1.1.5 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a long string of white spaces at the beginning of the ~/.pam_environment file.. EPSS estimates a 0.70% chance of exploitation in the next 30 days.
