A buffer overflow in PPP might allow a remote attacker to execute arbitrary code.
|Package||net-dialup/ppp on all architectures|
|Affected versions||< 2.4.8|
|Unaffected versions||>= 2.4.8|
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"
