Description

 Remote overflows exist in libxml2. libxml's nanoftp.c xmlNanoFTPConnect() and nanohttp.c xmlNanoHTTPConnectHost() functions fail to properly perform boundary checking of DNS replies, an issue that could potentially cause stack-based overflows. Using specially-crafted DNS replies, an attacker that has hijacked or is controlling a DNS server can cause a denial of service or execute arbitrary code, resulting in a loss of availability or integrity.

Classification

 Location: Remote/Network Access Required

Impact: Loss of Integrity, Loss of Availability
Exploit: Exploit Unknown
Disclosure: OSVDB Verified
