Attack conditions (Vendor/CNA, CVSS 3.1): Network (remote) · Low privileges required · No user interaction required

What an attacker can do

An authenticated attacker could cause a denial of service through a specially crafted message that triggers excessive memory operations during character set conversion. Vendor/CNA’s CVSS 3.1 assessment (base score 5.3/10) rates confidentiality and integrity impact as none; availability impact as high.
