Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200406-09
(Horde-Chora: Remote code execution)

A vulnerability in the diff viewer of Chora allows an attacker to inject
shellcode. An attacker can exploit PHP's file upload functionality to
upload a malicious binary to a vulnerable server, chmod it as executable,
and run the file.

Impact :

An attacker could remotely execute arbitrary binaries with the permissions
of the PHP script, conceivably allowing further exploitation of local
vulnerabilities and remote root access.

Workaround :

There is no known workaround at this time.
