CVE-2006-2194
NVD-CWE-OtherPublished: July 5, 2006· Updated: Jun 16, 2026
7.2
CVSS v3.1
Official Description
The winbind plugin in pppd for ppp 2.4.4 and earlier does not check the return code from the setuid function call, which might allow local users to gain privileges by causing setuid to fail, such as exceeding PAM limits for the maximum number of user processes, which prevents the winbind NTLM authentication helper from dropping privileges.
Technical Analysis
CVE-2006-2194 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
