Description


Debian Security Advisory DSA 1106-1 security@debian.org http://www.debian.org/security/ Martin Schulze July 10th, 2006 http://www.debian.org/security/faq


Package : ppp Vulnerability : programming error Problem type : local Debian-specific: no CVE ID : CVE-2006-2194

Marcus Meissner discovered that the winbind plugin in pppd does not check whether a setuid() call has been successful when trying to drop privileges, which may fail with some PAM configurations.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 2.4.3-20050321+2sarge1.

For the unstable distribution (sid) this problem has been fixed in version 2.4.4rel-1.

We recommend that you upgrade your ppp package.
