Insufficient memory write check in SMM service for EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6920-1 advisory.

    It was discovered that EDK II was not properly performing bounds checks in Tianocompress, which could lead     to a buffer overflow. An authenticated user could use this issue to potentially escalate their privileges     via

    local access. (CVE-2017-5731)

    It was discovered that EDK II had an insufficient memory write check in the SMM service, which could lead     to a page fault occurring. An

    authenticated user could use this issue to potentially escalate their privileges, disclose information     and/or create a denial of service via local access. (CVE-2018-12182)

    It was discovered that EDK II incorrectly handled memory in DxeCore, which could lead to a stack overflow.
    An unauthenticated user could this issue to potentially escalate their privileges, disclose information

    and/or create a denial of service via local access. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2018-12183)

    It was discovered that EDK II incorrectly handled memory in the Variable service under certain     circumstances. An authenticated user could use this issue to potentially escalate their privileges,     disclose

    information and/or create a denial of service via local access. (CVE-2018-3613)

    It was discovered that EDK II incorrectly handled memory in its system firmware, which could lead to a     buffer overflow. An unauthenticated user could use this issue to potentially escalate their privileges     and/or

    create a denial of service via network access. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-0160)

According to the versions of the edk2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - EFI Development Kit II AARCH64 UEFI FirmwareSecurity     Fix(es):AuthenticodeVerify() calls OpenSSLs d2i_PKCS7()     API to parse asn encoded signed authenticode pkcs#7     data. when this successfully returns, a type check is     done by calling PKCS7_type_is_signed() and then     Pkcs7->d.sign->contents->type is used. It is possible     to construct an asn1 blob that successfully decodes and     have d2i_PKCS7() return a valid pointer and have     PKCS7_type_is_signed() also return success but have     Pkcs7->d.sign be a NULL     pointer.(CVE-2019-14584)IA32_FEATURE_CONTROL stays     unlocked in S3 after a warm reset(CVE-2019-14588)We     have found a TOCTOU vulnerability which allows an     attacker with physical access to achieve code execution     after the Boot Guard ACM computes and validates the     hash of the IBB and measured the firmware into the TPM     PCR0. This means the firmware will be marked as valid     and have normal PCR0 values even though unsigned code     has run. The root cause is when the FSP has finished     memory init and disables MTRRs (and thereby the cache)     in order to switch off No Evict Mode. The code doing     this (the SecCore PeiTemporaryRamDonePpi callback), is     executed directly from SPI flash, allowing an attacker     to intercept execution flow. As a proof of concept we     demonstrated that using an FPGA to substitute a single,     targeted SPI transaction we can gain code     execution.(CVE-2019-11098)Insufficient control flow     management in BIOS firmware for 8th, 9th, 10th     Generation Intel(R) Core(TM), Intel(R) Celeron(R)     Processor 4000 & 5000 Series Processors may allow an     authenticated user to potentially enable denial of     service via adjacent access.(CVE-2019-14558)Logic issue     EDK II may allow an unauthenticated user to potentially     enable denial of service via adjacent     access.(CVE-2019-14587)Use after free vulnerability in     EDK II may allow an authenticated user to potentially     enable escalation of privilege, information disclosure     and/or denial of service via adjacent     access.(CVE-2019-14586)A NULL Pointer Dereference in     match_at() in regexec.c in Oniguruma 6.9.2 allows     attackers to potentially cause denial of service by     providing a crafted regular expression. Oniguruma     issues often affect Ruby, as well as common optional     libraries for PHP and Rust.(CVE-2019-13225)A     use-after-free in onig_new_deluxe() in regext.c in     Oniguruma 6.9.2 allows attackers to potentially cause     information disclosure, denial of service, or possibly     code execution by providing a crafted regular     expression. The attacker provides a pair of a regex     pattern and a string, with a multi-byte encoding that     gets handled by onig_new_deluxe(). Oniguruma issues     often affect Ruby, as well as common optional libraries     for PHP and Rust.(CVE-2019-13224)Insufficient memory     write check in SMM service for EDK II may allow an     authenticated user to potentially enable escalation of     privilege, information disclosure and/or denial of     service via local access.(CVE-2018-12182)Logic issue in     DxeImageVerificationHandler() for EDK II may allow an     authenticated user to potentially enable escalation of     privilege via local access.(CVE-2019-14575)Uncontrolled     resource consumption in EDK II may allow an     unauthenticated user to potentially enable denial of     service via network access.(CVE-2019-14559)Integer     truncation in EDK II may allow an authenticated user to     potentially enable escalation of privilege via local     access.(CVE-2019-14563)Improper authentication in EDK     II may allow a privileged user to potentially enable     information disclosure via network     access.(CVE-2019-14553)
