Description


Yuuichi Teranishi has discovered some vulnerabilities in libxml2, which potentially can be exploited by malicious people to compromise a vulnerable system.

The vulnerabilities are caused due to boundary errors in nanohttp and nanoftp when parsing overly long URIs. This can be exploited to cause a buffer overflow by supplying an overly long URI (about 4096 bytes).

Successful exploitation may potentially allow execution of arbitrary code.


Solution:
Update to version 2.6.6 or later.
