Description
In the Linux kernel, the following vulnerability has been resolved:
ipvs: reject invalid states in connection template sync records
IPVS sync receivers validate protocol states before creating or updating a
connection. For connection templates, however, they only log states outside
the template state range and still store the value in the connection.
A template can be returned by ordinary connection lookup. TCP and SCTP then
use the invalid state as an index into their transition tables.
Reject invalid template states in both sync protocol versions before
looking up or modifying a connection. The version 1 path handles both
IPv4 and IPv6 records.
