TITLE

libnet6 of inc/server.hpp of libobby Vulnerability in server where important information is obtained

DESCRIPTION

The libobby server in inc/server.hpp in libnet6 (aka net6) before 1.3.14 does not perform authentication before checking the user name, which allows remote attackers to obtain sensitive information such as server-usage patterns by a particular user and color preferences. Net6 is a simple network library. The net6 library performs certain operations before verifying the connection of user authentication information, which may result in the disclosure of part of the information of the connected user. net6 is prone to a session-hijacking vulnerability and an information-disclosure vulnerability. An attacker can exploit these vulnerabilities to obtain sensitive information, or possibly perform actions with elevated privileges. net6 1.3.13 is vulnerable; other versions may also be affected. For more information: SA46605 SOLUTION: Apply updated packages via the yum utility ("yum update net6"). ---------------------------------------------------------------------- Ovum says ad hoc tools are out-dated.
