Synopsis ========
A buffer overflow in PPP might allow a remote attacker to execute arbitrary code.
Background ==========
PPP is a Unix implementation of the Point-to-Point Protocol.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/ppp < 2.4.8 >= 2.4.8
Description ===========
It was discovered that bounds check in PPP for the rhostname was improperly constructed in the EAP request and response functions.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All PPP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/ppp-2.4.8"
