<title>Ghostscript: Insecure temporary file use in multiple scripts</title>
|
|
<synopsis>
|
|
Multiple scripts in the Ghostscript package are vulnerable to symlink
|
|
attacks, potentially allowing a local user to overwrite arbitrary files
|
|
with the rights of the user running the script.

|
|
drivers for various file formats and printers.

The pj-gs.sh, ps2epsi, pv.sh and sysvlp.sh scripts create temporary files
|
|
in world-writeable directories with predictable names.

<impact type="normal">
|
|
<p>
|
|
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.

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