- --------------------------------------------------------------------------Debian Security Advisory DSA 679-1 security@debian.org 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.
