Vulnerability Assessment Details

MDKSA-2003:029: 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-2003:029 (snort).

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
