GLSA 200404-19: Buffer overflows and format string vulnerabilities in LCDproc

http://security.gentoo.org/

Severity:	normal
Title:	Buffer overflows and format string vulnerabilities in LCDproc
Date:	04/27/2004
Bugs:	#47340
ID:	200404-19

Synopsis

Multiple remote vulnerabilities have been found in the LCDd server, allowing execution of arbitrary code with the rights of the LCDd user.

Background

LCDproc is a program that displays various bits of real-time system information on an LCD. It makes use of a local server (LCDd) to collect information to display on the LCD.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-misc/lcdproc	<= 0.4.4-r1	>= 0.4.5	All supported architectures

Description

Due to insufficient checking of client-supplied data, the LCDd server is susceptible to two buffer overflows and one string buffer vulnerability. If the server is configured to listen on all network interfaces (see the Bind parameter in LCDproc configuration), these vulnerabilities can be triggered remotely.

Impact

These vulnerabilities allow an attacker to execute code with the rights of the user running the LCDproc server. By default, this is the "nobody" user.

Workaround

A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.

Resolution

LCDproc users should upgrade to version 0.4.5 or later:

    # emerge sync

    # emerge -pv ">=app-misc/lcdproc-0.4.5"
    # emerge ">=app-misc/lcdproc-0.4.5"
