Description

In FreeBSD 12.0-RELEASE before 12.0-RELEASE-p13, a missing check in the ipsec packet processor allows reinjection of an old packet to be accepted by the ipsec endpoint. Depending on the higher-level protocol in use over ipsec, this could allow an action to be repeated.

Affected products

FreeBSD: 12.0, 12.0-p1, 12.0-p10, 12.0-p11, 12.0-p12, 12.0-p2 (+6)
