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-7.07.1-r7"
# emerge ">=app-text/ghostscript-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-7.05.6-r2"
# emerge ">=app-text/ghostscript-7.05.6-r2"


Risk factor : Medium
