CVE-2003-0364

CVE-2003-0364 affects the Linux kernel 2.4 series: TCP/IP fragment reassembly handling can be abused by crafted packets to trigger high CPU usage via hash table collisions, leading to a denial of service. Debians OpenVAS entries reference kernel updates (e.g., kernel-patch-2.4.18-powerpc, kernel-...

CVE-2003-0209

CVE-2003-0209 : Snort 2.0 and earlier contains an integer overflow in the TCP stream4 preprocessor used for TCP stream reassembly. This heap-based overflow can be exploited remotely via large TCP sequence numbers to execute arbitrary code, typically as the Snort user (likely root). Multiple sourc...
