Attack conditions (NVD, CVSS 3.1): Network (remote) · No privileges required · No user interaction required

What an attacker can do

Remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. NVD’s CVSS 3.1 assessment (base score 7.5/10) rates confidentiality and availability impact as none; integrity impact as high.
