ID: 200612-13

Synopsis
=======
libgsf improperly allocates memory allowing for a heap overflow and
possibly the execution of arbitrary code.
Background
=========
The GNOME Structured File Library is an I/O library that can read and
write common file types and handle structured formats that provide
file-system-in-a-file semantics.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 gnome-extra/libgsf < 1.14.2 >= 1.14.2
Description
==========
"infamous41md" has discovered that the "ole_init_info" function may
allocate too little memory for storing the contents of an OLE document,
resulting in a heap buffer overflow.
Impact
=====
An attacker could entice a user to open a specially crafted OLE
document, and possibly execute arbitrary code with the rights of the
user opening the document.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All libgsf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-extra/libgsf-1.14.2"
