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.
