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

high Nessus Plugin ID 27885

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

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