11Subject: [Qemu-devel] [PATCH 1/2] slirp: correct size computation while concatenating mbuf
12Date: Tue, 5 Jun 2018 23:38:35 +0530
13From: Prasad J Pandit <address@hidden>
14
15While reassembling incoming fragmented datagrams, 'm_cat' routine
16extends the 'mbuf' buffer, if it has insufficient room. It computes
17a wrong buffer size, which leads to overwriting adjacent heap buffer
18area. Correct this size computation in m_cat.
