MDKSA-2003:052: snort

Vulnerability Assessment Summary Check for the version of the snort package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory MDKSA-2003:052 (snort). An integer overflow was discovered in the Snort stream4 preprocessor by the Sourcefire Vulnerability Research Team. This preprocessor (spp_stream4) incorrectly calculates segment size parameters during stream reassembly for certainm sequence number ranges. This can lead to an integer overflow that can in turn lead to a heap overflow that can be exploited to perform a denial of service (DoS) or even remote command excution on the host running Snort. Disabling the stream4 preprocessor will make Snort invulnerable to this attack, and the flaw has been fixed upstream in Snort version 2.0. Snort versions 1.8 through 1.9.1 are vulnerable.
