Snort problems
Noel Davis looks at buffer overflows in Snort and SheerDNS, and problems in Xinetdvixie-cron, Oracle E-Business Suite FNDFS, xfsdump, Ximian Evolution, GtkHTML, kdegraphics, and psbanner.
Snort, a network-intrusion detection system, has a vulnerability in the stream4 preprocessor module that can be exploited by a remote attacker to execute arbitrary code with the permissions of the user that is running Snort (in most cases, root). The stream4 module puts TCP traffic back together when it has been fragmented across multiple TCP segments prior to it being analyzed.
It is recommended that users upgrade Snort to version 2.0 or newer as soon as possible. A workaround for this vulnerability is to comment out the line "preprocessor stream4_reassemble" in the Snort configuration file. This workaround will protect the server from this vulnerability, but it will make it easier to evade the intrusion detection system by fragmenting an attack across different TCP segments.
