descriptionSean Finney discovered several insecure temporary file uses in toolchain-source, the GNU binutils and GCC source code and scripts. These bugs can lead a local attacker with minimal knowledge to trick the admin into overwriting arbitrary files via a symlink attack. The problems exist inside the Debian-specific tpkg-* scripts.
