Vulnerability Scan Summary
libxml2: Remotely exploitable buffer overflow
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200411-05
(libxml2: Remotely exploitable buffer overflow)
Multiple buffer overflows have been detected in the nanoftp and nanohttp
modules. These modules are responsible for parsing URLs with ftp
information, and resolving names via DNS.

parse a specially-crafted XML file, potentially causing remote execution of
arbitrary code.
Workaround
There is no known workaround at this time.
