Description

Mac OS X pppd contains a flaw that may allow a malicious user to read CHAP or PAP authentication credentials in the pppd process.

By sending a specially crafted command line argument, a local attacker can read arbitrary data in pppd process, including the user's PAP/CHAP authentication credentials.
