Description

A flaw was found in PHP. Some functions, including `urldecode()`, incorrectly pass signed characters to character type (ctype) functions. On certain systems, this can lead to accessing memory with a negative offset. This vulnerability can be exploited by an attacker to trigger a denial of service (DoS), making the affected PHP application or system unavailable.
