GLSA-200501-43 : f2c: Insecure temporary file creation

low Nessus Plugin ID 16434

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-43 (f2c: Insecure temporary file creation)

Javier Fernandez-Sanguino Pena from the Debian Security Audit Team discovered that f2c creates temporary files in world-writeable directories with predictable names.
Impact :

A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem.
When f2c is executed, this would result in the file being overwritten with the rights of the user running the software, which could be the root user.
Workaround :

There is no known workaround at this time.

Solution

All f2c users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/f2c-20030320-r1'
