PPP is a Unix implementation of the Point-to-Point Protocol.
It was discovered that bounds check in PPP for the rhostname was improperly constructed in the EAP request and response functions.
A remote attacker, by sending specially crafted authentication data, could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All PPP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/ppp-2.4.8"
OS | Version | Architecture | Package | Version | Filename |
