Debian Security Advisory DSA 679-1 [email protected]http://www.debian.org/security/ Martin Schulze
February 14th, 2005 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
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.
Upgrade Instructions
- --------------------
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
