Logic error in FV parsing in MdeModulePkg\Core\Pei\FwVol\FwVol.c (CVE-2018-3630)

Logic issue in variable service module for EDK II/UDK2018/UDK2017/UDK2015 may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access. (CVE-2017-5734)

A missing check leads to an out-of-bounds read and write flaw in NetworkPkg/DnsDxe as shipped in edk2, when it parses DNS responses. A remote attacker who controls the DNS server used by the vulnerable firmware may use this flaw to make the system crash. (CVE-2018-3613)

improper DNS packet size check (CVE-2018-12178)

Privilege escalation via heap-based buffer overflow in Decode() function (CVE-2017-5735)

Privilege escalation via heap-based buffer overflow in MakeTable() function (CVE-2017-5733)

Privilege escalation via processing of malformed files in TianoCompress.c (CVE-2017-5731)

Privilege escalation via processing of malformed files in BaseUefiDecompressLib.c (CVE-2017-5732)

A stack-based buffer overflow was discovered in edk2 when the HII database contains a Bitmap that claims to be 4-bit or 8-bit per pixel, but the palette contains more than 16(2^4) or 256(2^8) colors.
(CVE-2018-12181)

Buffer overflow in BlockIo service for EDK II may allow an unauthenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via network access.
(CVE-2018-12180)

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-2125 advisory.

  - Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to     timing attacks via a side-channel timing attack on 'port contention'. (CVE-2018-5407)

  - Bounds checking in Tianocompress before November 7, 2017 may allow an authenticated user to potentially     enable an escalation of privilege via local access. (CVE-2017-5731)

  - Stack overflow in corrupted bmp for EDK II may allow unprivileged user to potentially enable denial of     service or elevation of privilege via local access. (CVE-2018-12181)

  - Stack overflow in XHCI for EDK II may allow an unauthenticated user to potentially enable denial of     service via local access. (CVE-2019-0161)

  - Logic issue in variable service module for EDK II/UDK2018/UDK2017/UDK2015 may allow an authenticated user     to potentially enable escalation of privilege, information disclosure and/or denial of service via local     access. (CVE-2018-3613)

  - Buffer overflow in system firmware for EDK II may allow unauthenticated user to potentially enable     escalation of privilege and/or denial of service via network access. (CVE-2019-0160)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
