GLSA 200409-25: CUPS: Denial of service vulnerability

Severity:normal
Title:CUPS: Denial of service vulnerability
Date:09/20/2004
Bugs: #64168
ID:200409-25

Synopsis

A vulnerability in CUPS allows remote attackers to cause a denial of service when sending a carefully-crafted UDP packet to the IPP port.

Background

The Common UNIX Printing System (CUPS) is a cross-platform print spooler.

Affected packages

Package Vulnerable Unaffected Architecture(s)
net-print/cups < 1.1.20-r2 >= 1.1.20-r2 All supported architectures

Description

Alvaro Martinez Echevarria discovered a hole in the CUPS Internet Printing Protocol (IPP) implementation that allows remote attackers to cause CUPS to stop listening on the IPP port.

Impact

A remote user with malicious intent can easily cause a denial of service to the CUPS daemon by sending a specially-crafted UDP datagram packet to the IPP port.

Workaround

There is no known workaround at this time.

Resolution

All CUPS users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=net-print/cups-1.1.20-r2"
    # emerge ">=net-print/cups-1.1.20-r2"
