Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_sip: widen NAT
rewrite delta to s32 in sip_help_tcp() sip_help_tcp() stores the size change of each NAT-rewritten SIP
message in s16 diff and accumulates it in s16 tdiff, but a single message can grow by more than S16_MAX
while the packet stays under the 65535 enlarge_skb() limit: nf_nat_sip() rewrites every matching URI, and
a long Contact list expands the message by tens of kilobytes. diff then wraps, and "datalen = datalen +
diff - msglen" yields a huge unsigned datalen, so the next iteration's ct_sip_get_header() reads past the
linearized skb tail. Widen diff, tdiff and the seq_adjust hook to s32. Both are bounded by the 65535 byte
packet limit, and the seqadj core is already s32 (nf_ct_seqadj_set() takes s32), so no previously accepted
input is rejected. BUG: KASAN: use-after-free in ct_sip_get_header (net/netfilter/nf_conntrack_sip.c:464)
