Package : toolchain-source
Vulnerability : insecure temporary files
Problem-Type : local
Debian-specific: yes
CVE ID : CAN-2005-0159

Sean 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.

For the stable distribution (woody) these problems have been fixed in
version 3.0.4-1woody1.

For the unstable distribution (sid) these problems have been fixed in
version 3.4-5.

We recommend that you upgrade your toolchain-source package.
