GLSA-200410-18 : Ghostscript: Insecure temporary file use in multiple scripts

high Nessus Plugin ID 15527

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-200410-18 (Ghostscript: Insecure temporary file use in multiple scripts)

The pj-gs.sh, ps2epsi, pv.sh and sysvlp.sh scripts create 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 an affected script is called, this would result in the file to be 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

Ghostscript users on all architectures except PPC should upgrade to the latest version:
# emerge sync # emerge -pv '>=app-text/ghostscript-esp-7.07.1-r7' # emerge '>=app-text/ghostscript-esp-7.07.1-r7' Ghostscript users on the PPC architecture should upgrade to the latest stable version on their architecture:
# emerge sync # emerge -pv '>=app-text/ghostscript-esp-7.05.6-r2' # emerge '>=app-text/ghostscript-esp-7.05.6-r2'
