Mandrake Linux Security Advisory : snort (MDKSA-2003:029)

critical Nessus Plugin ID 14013

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

A buffer overflow was discovered in the snort RPC normalization routines by ISS-XForce which can cause snort to execute arbitrary code embedded within sniffed network packets. The rpc_decode preprocessor is enabled by default. The snort developers have released version 1.9.1 to correct this behaviour; snort versions from 1.8 up to 1.9.0 are vulnerable.

For those unable to upgrade, you can disable the rpc_decode preprocessor by commenting out the line (place a '#' character at the beginning of the line) that enables it in your snort.conf file :

preprocessor rpc_decode

Solution

Update the affected packages.
