Detailsinfo

A vulnerability was found in Linux-PAM 1.1.2. It has been rated as critical. This issue affects an unknown part. The manipulation with an unknown input leads to a symlink vulnerability. Using CWE to declare the problem leads to CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. Impacted is confidentiality. The summary by CVE is:

The privilege-dropping implementation in the (1) pam_env and (2) pam_mail modules in Linux-PAM (aka pam) 1.1.2 does not perform the required setfsgid and setgroups system calls, which might allow local users to obtain sensitive information by leveraging unintended group permissions, 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.

The weakness was presented 01/24/2011 as Bug 641361 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. The identification of this vulnerability is CVE-2010-3430. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 59704 (GLSA-201206-31 : Linux-PAM: Multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
