TITLE

libnet6 of inc/server.hpp Integer overflow vulnerability

DESCRIPTION

Integer overflow in inc/server.hpp in libnet6 (aka net6) before 1.3.14 might allow remote attackers to hijack connections and gain privileges as other users by making a large number of connections until the overflow occurs and an ID of another user is provided. Net6 is a simple network library. Net6 has an internal ID count overflow error that can be exploited to hijack other user sessions. 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.
