Gentoo Linux Security Advisory

Title: LessTif: Integer and stack overflows in libXpm (GLSA 200410-09)
Severity: normal
Exploitable: remote
Date: October 09, 2004
Bug(s): #66647
ID: 200410-09

Synopsis


Multiple vulnerabilities have been discovered in libXpm, which is included
in LessTif, that can potentially lead to remote code execution.


Background


LessTif is a clone of OSF/Motif, which is the standard user interface
toolkit available on Unix and Linux.


Affected Packages

Package: x11-libs/lesstif
Vulnerable: < 0.93.97
Unaffected: >= 0.93.97
Architectures: All supported architectures


Description


Chris Evans has discovered various integer and stack overflows in libXpm,
which is shipped as a part of the X Window System. LessTif, an application
that includes this library, is susceptible to the same issues.


Impact


A carefully-crafted XPM file could crash applications that are linked
against libXpm, such as LessTif, potentially allowing the execution of
arbitrary code with the privileges of the user running the application.


Workaround


There is no known workaround at this time.


Resolution


All LessTif users should upgrade to the latest version:
Code:
# emerge sync

    # emerge -pv ">=x11-libs/lesstif-0.93.97"
    # emerge ">=x11-libs/lesstif-0.93.97"
