CVE-2010-3431
1.9 · LOWOverview
CVE-2010-3431 is a low-severity vulnerability affecting linux-pam linux-pam. It was published on January 24, 2011 and has a CVSS 2.0 base score of 1.9 (LOW).
This vulnerability has a CVSS 2.0 base score of 1.9, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The privilege-dropping implementation in the (1) pam_env and (2) pam_mail modules in Linux-PAM (aka pam) 1.1.2 does not check the return value of the setfsuid system call, which might allow local users to obtain sensitive information by leveraging an unintended uid, as demonstrated by a symlink attack on the .pam_environment file in a user's home directory. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-3435.
Remediation
Check the references section for vendor advisories and patches from linux-pam. Update linux-pam to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
