Debian: New metrics packages fix insecure temporary file creation

Paul Szabo and Matt Zimmerman discoverd two similar problems in metrics, a tools for software metrics. Two scripts in this package, "halstead" and "gather_stats", open temporary files without taking appropriate security precautions. "halstead" is installed as a user program, while "gather_stats" is only used in an auxiliary script included in the source code. These vulnerabilities could allow a local attacker to overwrite files owned by the user running the scripts, including root. Fixed packages are available from security.debian.org.

Package        : metrics
Vulnerability  : insecure temporary file creation
Problem-Type   : local
Debian-specific: no
CVE Id         : CAN-2003-0202

Paul Szabo and Matt Zimmerman discoverd two similar problems in
metrics, a tools for software metrics.  Two scripts in this package,
"halstead" and "gather_stats", open temporary files without taking
appropriate security precautions.  "halstead" is installed as a user
program, while "gather_stats" is only used in an auxiliary script
included in the source code.  These vulnerabilities could allow a
local attacker to overwrite files owned by the user running the
scripts, including root.

The stable distribution (woody) is not affected since it doesn't
contain a metrics package anymore.

For the old stable distribution (potato) this problem has been fixed
in version 1.0-1.1.

The unstable distribution (sid) is not affected since it doesn't
contain a metrics package anymore.

We recommend that you upgrade your metrics package.
