-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : libnids SUMMARY : Remotely exploitable buffer overflow vulnerability DATE : 2003-10-29 16:46:00 ID : CLA-2003:773 RELEVANT RELEASES : 7.0, 8, 9 - ------------------------------------------------------------------------- DESCRIPTION Libnids[1] is an implementation of an E-component of Network Intrusion Detection Systems. It emulates the IP stack of the Linux kernel 2.0.x. Robert Watson found a buffer overflow vulnerability in the code responsible for TCP reassembly of libnids. A remote attacker may potentially exploit this vulnerability to execute arbitrary code in the context of the application using this functionality of libnids. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0850[2] to this issue. The problem has been fixed in libnids 1.18[3], which is included with this update. Also included with this update are new packages of dsniff, the only project which uses libnids in Conectiva Linux. SOLUTION All libnids users should upgrade.
