ipvs: avoid out-of-bounds write in ip_vs_nat_icmp<\/p>\n
Sashiko warns that local attacker can modify the packet
\nwhile it is processed by IPVS. Some places read the
\nIP ihl field multiple times which can cause out-of-bounds
\naccess. One such place is ip_vs_nat_icmp where we
\ncan write after the validated area.<\/p>\n
Fix it by providing ciph argument just like it is done for
\nIPv6 and use ciph->len as offset to the embedded transport
\nheader.<\/p>\n
Modify some IPv4 header checks by reading the ihl field
\nonly once.<\/p>\n","protected":false},"excerpt":{"rendered":"
