GLSA-200506-08 : GNU shtool, ocaml-mysql: Insecure temporary file creation

low Nessus Plugin ID 18465

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-200506-08 (GNU shtool, ocaml-mysql: Insecure temporary file creation)

Eric Romang has discovered that GNU shtool insecurely creates temporary files with predictable filenames (CAN-2005-1751). On closer inspection, Gentoo Security discovered that the shtool temporary file, once created, was being reused insecurely (CAN-2005-1759).
Impact :

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

There is no known workaround at this time.

Solution

All GNU shtool users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-util/shtool-2.0.1-r2' All ocaml-mysql users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-ml/ocaml-mysql-1.0.3-r1'
