A buffer overflow in PPP might allow a remote attacker to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |

| net-dialup/ppp | * | < 2.4.8 | >= 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"

PPP is a Unix implementation of the Point-to-Point Protocol
A buffer overflow was discovered in the rc_mksid function in plugins/radius/util.c in PPP when the PID for pppd is greater than 65535.
A remote attacker could 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-2.4.7-r3"
An integer overflow in PPP might allow local attackers to obtain sensitive information.

PPP is a Unix implementation of the Point-to-Point Protocol
Integer overflow is discovered in the getword function in options.c in PPP
A local attacker could execute process with extremely long options list, possibly obtaining sensitive information.
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-2.4.7"
