USN-7061-1: Go vulnerabilities

Read Time:1 Minute, 31 Second

Hunter Wittenborn discovered that Go incorrectly handled the sanitization
of environment variables. An attacker could possibly use this issue to run
arbitrary commands. (CVE-2023-24531)

Sohom Datta discovered that Go did not properly validate backticks (`) as
Javascript string delimiters, and did not escape them as expected. An
attacker could possibly use this issue to inject arbitrary Javascript code
into the Go template. (CVE-2023-24538)

Juho Nurminen discovered that Go incorrectly handled certain special
characters in directory or file paths. An attacker could possibly use
this issue to inject code into the resulting binaries. (CVE-2023-29402)

Vincent Dehors discovered that Go incorrectly handled permission bits.
An attacker could possibly use this issue to read or write files with
elevated privileges. (CVE-2023-29403)

Juho Nurminen discovered that Go incorrectly handled certain crafted
arguments. An attacker could possibly use this issue to execute arbitrary
code at build time. (CVE-2023-29405)

It was discovered that Go incorrectly validated the contents of host
headers. A remote attacker could possibly use this issue to inject
additional headers or entire requests. (CVE-2023-29406)

Takeshi Kaneko discovered that Go did not properly handle comments and
special tags in the script context of html/template module. An attacker
could possibly use this issue to inject Javascript code and perform a
cross-site scripting attack. (CVE-2023-39318, CVE-2023-39319)

It was discovered that Go did not limit the number of simultaneously
executing handler goroutines in the net/http module. An attacker could
possibly use this issue to cause a panic resulting in a denial of service.
(CVE-2023-39325)

It was discovered that the Go html/template module did not validate errors
returned from MarshalJSON methods. An attacker could possibly use this
issue to inject arbitrary code into the Go template. (CVE-2024-24785)

USN-7060-1: EDK II vulnerabilities

Read Time:1 Minute, 23 Second

It was discovered that EDK II did not check the buffer length in XHCI,
which could lead to a stack overflow. A local attacker could potentially
use this issue to cause a denial of service. This issue only affected
Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2019-0161)

Laszlo Ersek discovered that EDK II incorrectly handled recursion. A
remote attacker could possibly use this issue to cause EDK II to consume
resources, leading to a denial of service. This issue only affected
Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2021-28210)

Satoshi Tanda discovered that EDK II incorrectly handled decompressing
certain images. A remote attacker could use this issue to cause EDK II to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
(CVE-2021-28211)

It was discovered that EDK II incorrectly decoded certain strings. A remote
attacker could use this issue to cause EDK II to crash, resulting in a
denial of service, or possibly execute arbitrary code. This issue only
affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2021-38575)

It was discovered that EDK II had integer underflow vulnerability in
SmmEntryPoint, which could result in a buffer overflow. An attacker
could potentially use this issue to cause a denial of service.
(CVE-2021-38578)

Elison Niven discovered that OpenSSL, vendored in EDK II, incorrectly
handled the c_rehash script. A local attacker could possibly use this
issue to execute arbitrary commands when c_rehash is run. This issue
only affected Ubuntu 16.04 LTS. (CVE-2022-1292)
