Vulnerability Assessment Details

[GLSA-200411-05] libxml2: Remotely exploitable buffer overflow

Vulnerability Assessment Summary
libxml2: Remotely exploitable buffer overflow

Detailed Explanation for this Vulnerability Assessment
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.

Impact

A possible hacker could exploit an application that uses libxml2 by forcing it to
parse a specially-crafted XML file, potentially causing remote execution of
arbitrary code.

Workaround

There is no known workaround at this time.
