Netpbm is a package of 220 graphics programs and a programming
|
|
libraries, including pstopnm. pstopnm is a tool which converts
|
|
PostScript files to PNM image files.

<description>
|
|
<p>
|
|
Max Vozeler reported that pstopnm calls the GhostScript interpreter on
|
|
untrusted PostScript files without specifying the -dSAFER option, to
|
|
convert a PostScript file into a PBM, PGM, or PNM file.
|
|
</p>
|
|

|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could craft a malicious PostScript file and entice a user
|
|
to run pstopnm on it, resulting in the execution of arbitrary commands
|
|
with the permissions of the user running pstopnm.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Netpbm users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose media-libs/netpbm</code>
|
