[GLSA]

Gentoo Linux Security Advisory

Title: Buffer overflows and format string vulnerabilities in LCDproc (GLSA 200404-19)
Severity: normal
Exploitable: remote
Date: April 27, 2004
Bug(s): #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: app-misc/lcdproc
Vulnerable: <= 0.4.4-r1
Unaffected: >= 0.4.5
Architectures: 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:
