OESA-2022-2115 (CVE-2022-41716)

Vulnerability from osv_openeuler – Published: 2022-11-25 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

golang security update

Details

The Go Programming Language.

Security Fix(es):

Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" sets the variables "A=B" and "C=D".(CVE-2022-41716)

Severity

7.5 (High)
