Title:	OpenMotif, AMD64 x86 emulation X libraries: Buffer overflows in libUil library
Date:	12/28/2005
Bugs:	#114234, #116481
ID:	200512-16

Synopsis

Two buffer overflows have been discovered in libUil, part of the OpenMotif toolkit, that can potentially lead to the execution of arbitrary code.

Background

OpenMotif provides a free version of the Motif toolkit for open source applications. The OpenMotif libraries are included in the AMD64 x86 emulation X libraries, which emulate the x86 (32-bit) architecture on the AMD64 (64-bit) architecture.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
x11-libs/openmotif	< 2.2.3-r8	>= 2.2.3-r8	All supported architectures
app-emulation/emul-linux-x86-xlibs	< 2.2.1	>= 2.2.1	AMD64

Description

xfocus discovered two potential buffer overflows in the libUil library, in the diag_issue_diagnostic and open_source_file functions.

Impact

Remotely-accessible or SUID applications making use of the affected functions might be exploited to execute arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All OpenMotif users should upgrade to an unaffected version:

    # emerge --sync
    # emerge --ask --oneshot --unmerge --verbose x11-libs/openmotif
    # emerge --ask --oneshot --verbose x11-libs/openmotif

All AMD64 x86 emulation X libraries users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose app-emulation/emul-linux-x86-xlibs
