uutils coreutils env Local Denial of Service via Improper Handling of Backslashes in Split-String Mode

A logic error in the env utility of uutils coreutils causes a failure to correctly parse command-line arguments when utilizing the -S (split-string) option. In GNU env, backslashes within single quotes are treated literally (with the exceptions of \\ and \'). However, the uutils implementation incorrectly attempts to validate these sequences, resulting in an "invalid sequence" error and an immediate process termination with an exit status of 125 when encountering valid but unrecognized sequences like \a or \x. This divergence from GNU behavior breaks compatibility for automated scripts and administrative workflows that rely on standard split-string semantics, leading to a local denial of service for those operations.

输入验证不恰当

uutils coreutils 输入验证错误漏洞

uutils coreutils是Uutils开源的一个跨平台核心命令行工具集。 uutils coreutils存在输入验证错误漏洞，该漏洞源于env逻辑错误，在使用-S选项时未能正确解析命令行参数，可能导致本地拒绝服务。
