Description

A remote overflow exists in Libxml2. Libxml2's nanoftp.c xmlNanoFTPScanProxy() function fails to perform boundary checking of user-supplied data that is copied into a finite stack buffer, which could potentially cause a stack-based overflow. Using a specially crafted URL, an attacker can cause a denial of service or execute arbitrary code resulting in a loss of integrity or availability.
