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: nfnetlink_osf: fix divide-
 by-zero in OSF_WSS_MODULO nf_osf_match_one() computes ctx->window % f->wss.val in the OSF_WSS_MODULO
 branch with no guard for f->wss.val == 0. A CAP_NET_ADMIN user can add such a fingerprint via nfnetlink; a
 subsequent matching TCP SYN divides by zero and panics the kernel. Reject the bogus fingerprint in
 nfnl_osf_add_callback() above the per-option for-loop. f->wss is per-fingerprint, not per-option, so the
 check must run regardless of f->opt_num (including 0). Also reject wss.wc >= OSF_WSS_MAX;
 nf_osf_match_one() already treats that as "should not happen". Crash: Oops: divide error: 0000 [#1] SMP
