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.
"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.
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.
There is no known workaround at this time.
All libgsf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-extra/libgsf-1.14.2"
