"It was discovered that there was a NULL pointer deference exploit in
libgsf, a I/O abstraction library for GNOME.

An error within the 'tar_directory_for_file()' function could be
exploited to trigger a NULL pointer dereference and subsequently cause
a crash via a crafted TAR file.

For Debian 7 'Wheezy', this issue has been fixed in libgsf version
1.14.21-2.1+deb7u1.

We recommend that you upgrade your libgsf packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
