Debian DSA-620-1 : perl - insecure temporary files / directories

low Nessus Plugin ID 16073

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in Perl, the popular scripting language. The Common Vulnerabilities and Exposures project identifies the following problems :

- CAN-2004-0452 Jeroen van Wolffelaar discovered that the rmtree() function in the File::Path module removes directory trees in an insecure manner which could lead to the removal of arbitrary files and directories through a symlink attack.

- CAN-2004-0976

Trustix developers discovered several insecure uses of temporary files in many modules which allow a local attacker to overwrite files via a symlink attack.

Solution

Upgrade the perl packages.

For the stable distribution (woody) these problems have been fixed in version 5.6.1-8.8.
