Name of the Vulnerable Software and Affected Versions
Linux-PAM versions prior to 1.1.2
Description
The issue is related to the
run coprocess function in pam xauth.c in the pam xauth module, which does not check the return values of the setuid, setgid, and setgroups system calls. This might allow local users to read arbitrary files by executing a program that relies on the pam xauth PAM check. The vulnerability can be exploited locally and may lead to a violation of confidentiality, integrity, and availability of protected information.Recommendations
For Linux-PAM versions prior to 1.1.2, update to version 1.1.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the
pam xauth module until a patch is available. Avoid using the pam xauth PAM check in sensitive applications until the issue is resolved.Correção
