Hi,
ipset 7.5 is just released - please upgrade to this version! The syzkaller
fuzzer discovered a NULL dereference bug in ipset, which was fixed by
Florian Westphal. The CAP_NET_ADMIN capability is required to exploit the
vulnerability. Other than that, the release brings a lot of backward
compatibility improvements, thanks to Serhey Popovych.
Userspace changes:
- configure.ac: Support building with old autoconf 2.63
(Serhey Popovych)
- configure.ac: Build on kernels without skb->vlan_proto correctly
(Serhey Popovych)
- configure.ac: Add cond_resched_rcu() checks (Serhey Popovych)
- configure.ac: Better match for ipv6_skip_exthdr() frag_offp
arg presence (Serhey Popovych)
- Document explicitly that protocol is not stored in bitmap:port
Kernel part changes:
- netfilter: ipset: avoid null deref when IPSET_ATTR_LINENO is present
(Florian Westphal)
- ip_set: Pass init_net when @net is missing in match check params
data structure (Serhey Popovych)
- netfilter: xt_set: Do not restrict --map-set to the mangle table
(Serhey Popovych)
- compat: em_ipset: Build on old kernels (Serhey Popovych)
- compat: Use skb_vlan_tag_present() instead of vlan_tx_tag_present()
(Serhey Popovych)
