4 vulnerabilities found for wget2 by gnu

CVE-2025-69195 (GCVE-0-2025-69195)

Title
Wget2: gnu wget2: memory corruption and crash via filename sanitization logic with attacker-controlled urls
Summary
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.

Title
Wget2: arbitrary file write via metalink path traversal in gnu wget2
Summary
A security issue was discovered in GNU Wget2 when handling Metalink documents. The application fails to properly validate file paths provided in Metalink <file name> elements. An attacker can abuse this behavior to write files to unintended locations on the system. This can lead to data loss or potentially allow further compromise of the user’s environment.

Title
Wget2: gnu wget2: memory corruption and crash via filename sanitization logic with attacker-controlled urls
Summary
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.

Title
Wget2: arbitrary file write via metalink path traversal in gnu wget2
Summary
A security issue was discovered in GNU Wget2 when handling Metalink documents. The application fails to properly validate file paths provided in Metalink <file name> elements. An attacker can abuse this behavior to write files to unintended locations on the system. This can lead to data loss or potentially allow further compromise of the user’s environment.
