CUPS < 1.3.9 Multiple Vulnerabilities

High

Synopsis

The remote printer service is affected by multiple vulnerabilities.

Description

According to its banner, the version of CUPS installed on the remote host is earlier than 1.3.9. Such versions are affected by several issues :

- The HP-GL/2 filter does not adequately check the ranges on the pen width and pen color opcodes, which allows an attacker to overwrite memory addresses with arbitrary data and which may result in execution of arbitrary code (STR #2911). - There is a heap-based buffer overflow in the SGI file format parsing module that can be triggered with malformed Run Length Encoded (RLE) data to execute arbitrary code (STR #2918). - There is an integer overflow vulnerability in the 'WriteProlog()' function in the 'texttops' application that can be triggered when calculating the page size used for storing PostScript data to execute arbitrary code (STR #2919).

Solution

Upgrade to version 1.3.9 or higher.
