Ubuntu 5.10 / 6.06 LTS : ppp vulnerability (USN-310-1)

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Marcus Meissner discovered that the winbind plugin of pppd does not
check the result of the setuid() call. On systems that configure PAM
limits for the maximum number of user processes and enable the winbind
plugin, a local attacker could exploit this to execute the winbind
NTLM authentication helper as root. Depending on the local winbind
configuration, this could potentially lead to privilege escalation.

Solution :

Update the affected ppp, ppp-dev and / or ppp-udeb packages.

Risk factor :

High / CVSS Base Score : 7.2

Family: Ubuntu Local Security Checks
