Vulnerability Title
GNU Wget 1.25.0 Heap Buffer Underread via Metalink URL Parsing
Source: CVE Program / CVE List V5
Vulnerability Description
GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior.

GNU wget 缓冲区错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
GNU wget是美国GNU基金会开源的一个文件下载工具。 GNU wget 1.25.0及之前版本存在缓冲区错误漏洞，该漏洞源于src/metalink.c文件中的clean_metalink_string()函数存在堆缓冲区越界读取问题，当处理仅包含空格的Metalink URL时，可能导致指针递减超出缓冲区起始位置，恶意服务器可通过提供包含空格URL的Metalink文档触发内存破坏，可能导致异常程序行为。
