CVE-2023-52389
Estado: ModificadaCrítica (9.8)—
UTF32Encoding.cpp in POCO has a Poco::UTF32Encoding integer overflow and resultant stack buffer overflow because Poco::UTF32Encoding::convert() and Poco::UTF32::queryConvert() may return a negative integer if a UTF-32 byte sequence evaluates to a value of 0x80000000 or higher. This is fixed in 1.11.8p2, 1.12.5p2, and 1.13.0.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
