Doc Text:	A flaw was found in GNU Wget2. This vulnerability, a stack-based buffer overflow, occurs in the filename sanitization logic when processing attacker-controlled URL paths, particularly when filename restriction options are active. A remote attacker can exploit this by providing a specially crafted URL, which, upon user interaction with wget2, can lead to memory corruption. This can cause the application to crash and potentially allow for further malicious activities.	Story Points:	---

Description OSIDB Bzimport 2025-12-29 14:06:05 UTC

Stack-based buffer overflow vulnerability in the filename sanitization logic of GNU Wget2. The flaw occurs when wget2 processes attacker-controlled URL paths while filename restriction options such as --restrict-file-names=windows, unix, or ascii are enabled. During sanitization, the application writes beyond a fixed 1024-byte stack buffer due to missing bounds checks. A specially crafted URL path or HTTP redirect can trigger memory corruption, resulting in a crash or potentially enabling further exploitation. The issue can be triggered remotely with no authentication, requiring only user interaction to invoke wget2.
