Vulnerability Title
uutils coreutils expr Local Denial of Service via Eager Evaluation of Parenthesized Subexpressions
Source: NVD (National Vulnerability Database)
Vulnerability Description
A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR (|) and AND (&) operations. As a result, arithmetic errors (such as division by zero) occurring within "dead" branches, branches that should be ignored due to short-circuiting, are raised as fatal errors. This divergence from GNU expr behavior can cause guarded expressions within shell scripts to fail with hard errors instead of returning expected boolean results, leading to premature script termination and breaking GNU-compatible shell control flow.

Vulnerability Title
uutils coreutils 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
uutils coreutils是Uutils开源的一个跨平台核心命令行工具集。 uutils coreutils存在安全漏洞，该漏洞源于expr逻辑错误，在解析阶段而非执行阶段评估括号内的子表达式，导致无法对逻辑或和与操作进行正确的短路求值，可能造成脚本提前终止并破坏兼容的控制流。
