Hello, Libnids is a library which implements the functionality of NIDS E-component. Libnids provides IP defragmentation, TCP stream reassembly and port scan detection. Robert Watson <rwatson@FreeBSD.org> has found a bug in the part of libnids code responsible for TCP reassembly. The flaw probably allows for remote code execution. This vulnerability has been assigned a CVE name CAN-2003-0850. Applications not using libnids tcp reassembly (like scanlogd) are not vulnerable; others, like dsniff, are potentially vulnerable. All libnids versions <= 1.17 are vulnerable. Libnids 1.18, which fixes this issue, is available at http://libnids.sourceforge.net. Save yourself, Nergal
