Oracle Linux: CVE-2019-14378: ELSA-2019-3403: container-tools:ol8 security, bug fix, and enhancement update (IMPORTANT) (Multiple Advisories)

ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it mishandles a case involving the first fragment.
A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the ip_reass() routine while reassembling incoming packets if the first fragment is bigger than the m->m_dat[] buffer. An attacker could use this flaw to crash the QEMU process on the host, resulting in a Denial of Service or potentially executing arbitrary code with privileges of the QEMU process.
