If a user were tricked into running\nan untrusted kernel image, a remote attacker could possibly use this issue\nto run arbitrary code. This issue only affected Ubuntu 14.04 LTS.\n(CVE-2020-13765)\n\nAviv Sasson discovered that QEMU incorrectly handled Slirp networking. A\nremote attacker could use this issue to cause QEMU to crash, resulting in a\ndenial of service, or possibly execute arbitrary code. This issue only\naffected Ubuntu 14.04 LTS. (CVE-2020-1983)\n\nIt was discovered that the SLiRP networking implementation of the QEMU\nemulator did not properly manage memory under certain circumstances. An\nattacker could use this to cause a heap-based buffer overflow or other out-\nof-bounds access, which can lead to a denial of service (application crash)\nor potential execute arbitrary code. This issue only affected\nUbuntu 14.04 LTS. (CVE-2020-7039)\n\nIt was discovered that the SLiRP networking implementation of the QEMU\nemulator misuses snprintf return values.
