GLSA-200710-10 : SKK Tools: Insecure temporary file creation

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


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-200710-10
(SKK Tools: Insecure temporary file creation)

skkdic-expr.c insecurely writes temporary files to a location in the
form $TMPDIR/skkdic$PID.{pag,dir,db}, where $PID is the process ID.

Impact :

A local attacker could create symbolic links in the directory where the
temporary files are written, pointing to a valid file somewhere on the
filesystem that is writable by the user running the SKK software. When
SKK writes the temporary file, the target valid file would then be
overwritten with the contents of the SKK temporary file.

Workaround :

There is no known workaround at this time.

Solution :

All SKK Tools users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-i18n/skktools-1.2-r1'

Risk factor :

Medium / CVSS Base Score : 4.4
