Debian DSA-2326-1 : pam - several vulnerabilities

medium Nessus Plugin ID 56622
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Kees Cook of the ChromeOS security team discovered a buffer overflow in pam_env, a PAM module to set environment variables through the PAM stack, which allowed the execution of arbitrary code. An additional issue in argument parsing allows denial of service.

The oldstable distribution (lenny) is not affected.


Upgrade the pam packages.

For the stable distribution (squeeze), this problem has been fixed in version 1.1.1-6.1+squeeze1.
