Logic issue in DxeImageVerificationHandler() for EDK II may allow an authenticated user to potentially enable escalation of privilege via local access.

For Debian 9 stretch, these problems have been fixed in version 0~20161202.7bbe0b3e-1+deb9u2.

We recommend that you upgrade your edk2 packages.

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)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1510 advisory.

    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)

  - EDK2 is a set of cross-platform firmware development     environment based on UEFI and PI specifications in the     TianoCore community.An input verification error     vulnerability exists in EDK2. The vulnerability stems     from the fact that the network system or product did     not correctly verify the input data.(CVE-2019-14563)

  - EDK2 is a set of cross-platform firmware development     environment based on UEFI and PI specifications in the     TianoCore community.There is a security vulnerability     in EDK2. The source of the vulnerability will receive     an invalid certificate when HTTPS-over-IPv6 is started.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4349-1 advisory.

    A buffer overflow was discovered in the network stack. An unprivileged user could potentially enable     escalation of privilege and/or denial of service. This issue was already fixed in a previous release for     18.04 LTS and 19.10. (CVE-2018-12178)

    A buffer overflow was discovered in BlockIo service. An unauthenticated user could potentially enable     escalation of privilege, information disclosure and/or denial of service. This issue was already fixed in     a previous release for 18.04 LTS and 19.10. (CVE-2018-12180)

    A stack overflow was discovered in bmp. An unprivileged user could potentially enable denial of service or     elevation of privilege via local access. This issue was already fixed in a previous release for 18.04 LTS     and 19.10. (CVE-2018-12181)

    It was discovered that memory was not cleared before free that could lead to potential password leak.
    (CVE-2019-14558)
