streams. An attacker could possibly use this issue to cause a denial of
service. (CVE-2022-41723)

certain circumstances. An attacker could possibly use this issue to cause
a panic resulting in a denial of service. (CVE-2022-41724)

validate the amount of memory and disk files ReadForm can consume. An
attacker could possibly use this issue to cause a panic resulting in a
denial of service. (CVE-2022-41725)

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)

forms. An attacker could possibly use this issue to consume an excessive
amount of resources, resulting in a denial of service. (CVE-2023-24536)

characters in directory or file paths. An attacker could possibly use
this issue to inject code into the resulting binaries. (CVE-2023-29402)

handle a certificate chain which contains a certificate with an unknown
public key algorithm. An attacker could possibly use this issue to cause
a panic resulting into a denial of service. (CVE-2024-24783)

Juho Nurminen discovered that the Go net/mail module did not properly
handle comments within display names in the ParseAddressList function.
An attacker could possibly use this issue to cause a panic resulting into
a denial of service. (CVE-2024-24784)
