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 8 Jessie
, this problem has been fixed in version
1.14.30-2+deb8u1.
We recommend that you upgrade your libgsf packages.
